New executors #1007

This doesn't get rid of the flakiness entirely, but merely shifts things around and uses safer timings to reduce the possibility of failures. In my tests the behavior is much more stable now, though there are still issues on Windows during quick CPU usage bursts, which I'm hopeful we won't run into on GH Actions.

This does the same functional check as before in a simpler way, while also ensuring all values were covered, whereas in the previous version a sequence of repeating values that doesn't decrement would erroneously pass the test.

Make some executor tests more deterministic

@mstoykov

This ports @mstoykov's simpler implementation from https://github.com/loadimpact/k6/blob/9fa61d917c9f3bdfbb744ff6a40db2f851522098/lib/execution_segment_test.go#L506

Progress bars will now dynamically resize depending on terminal window width, being replaced with percentages if "squished" too far. It works best on *nix platforms because of SIGWINCH, while on Windows retrieving the size is required before each render iteration, and isn't as responsive. Terminal multiplexers are a bigger issue: tmux seems to buffer SIGWINCH/terminfo and is plain broken on versions including the current latest stable (3.0a) (see issue #2005[1]). This was fixed on `master`, but is yet to be released, and even with the fix the experience is far from ideal (lags quite a bit, no continuous resize). GNU screen also has some rendering issues I haven't looked too much into yet. Untested on macOS terminals, but I expect it to work as well as on Linux. Terminals tested: - Linux: st, urxvt, xterm - Windows: cmd.exe and PowerShell standalone, and both inside the new Windows Terminal[2] app. Resizing works fine in all cases, though isn't as responsive as on Linux.

See [1]. This also accidentally fixes [2], and the time.Sleep hack is not needed! [1]: #1332 (comment) [2]: #1332 (comment)

Resolves #1332 (comment)

Progress bars will be responsive by default, and fixed compact (showing percentages) only in non-interactive terminals (e.g. CI). Resolves #1332 (review)

This one handles ... more elegantly all cases where the execution segmetn sequence isn't full or missing at all. This is mostly done through the fact that the algorithm works even if we don't fill the sequence as long as we don't care about whether 0:1/3 and 1/3:2/3 get the same offsets when there is no sequence provided. If we care about that we need to fill the sequence which will be more involved but not by much :D. The other thing is that the construction of the numerator, steps and so on arrays is separate from the actual algorithm of calculating the offsets which at least makes silence golangci-lint. I would argue also makes it easier to read.

Very small speed up but it does also drop the memory usage in not "even" sequences. There are better algorithms for calculating the gcd but unless there are some quite big and divers denominators this will have very small perfomance impact if at all. name old time/op new time/op delta GetStripedOffsets/length10,seed777-4 4.50µs ±48% 3.48µs ±35% -22.59% (p=0.000 n=48+48) GetStripedOffsets/length100,seed777-4 1.94ms ±21% 1.81ms ±16% -6.87% (p=0.000 n=50+50) GetStripedOffsetsEven/length10-4 1.15µs ± 2% 1.08µs ± 1% -6.42% (p=0.000 n=43+43) GetStripedOffsetsEven/length100-4 15.0µs ± 1% 14.0µs ± 4% -6.80% (p=0.000 n=43+43) GetStripedOffsetsEven/length1000-4 377µs ± 1% 351µs ± 1% -6.80% (p=0.000 n=44+44) name old alloc/op new alloc/op delta GetStripedOffsets/length10,seed777-4 983B ±37% 764B ± 2% -22.20% (p=0.000 n=50+48) GetStripedOffsets/length100,seed777-4 10.4kB ±25% 7.9kB ± 3% -23.90% (p=0.000 n=50+49) GetStripedOffsetsEven/length10-4 576B ± 0% 576B ± 0% ~ (all equal) GetStripedOffsetsEven/length100-4 5.90kB ± 0% 5.90kB ± 0% ~ (all equal) GetStripedOffsetsEven/length1000-4 47.0kB ± 0% 47.0kB ± 0% ~ (all equal) name old allocs/op new allocs/op delta GetStripedOffsets/length10,seed777-4 25.1 ±67% 15.0 ± 0% -40.19% (p=0.000 n=50+50) GetStripedOffsets/length100,seed777-4 222 ±54% 105 ± 5% -52.88% (p=0.000 n=50+48) GetStripedOffsetsEven/length10-4 12.0 ± 0% 12.0 ± 0% ~ (all equal) GetStripedOffsetsEven/length100-4 72.0 ± 0% 72.0 ± 0% ~ (all equal) GetStripedOffsetsEven/length1000-4 472 ± 0% 472 ± 0% ~ (all equal)

This required some interface changes as well as a lot of test retouching. There is somewhat significant perfomance degradation which comes from the fact that now we calculate the offset for everything once, this should be negligible in the cases where it is not needed and when it is it is going to significantly speed up the execution. The constant arrival rate executor has been used to showcase how the striping algorithm should be used. name old time/op new time/op delta GetStripedOffsets/length10,seed777-4 3.64µs ±40% 5.56µs ±33% +52.95% (p=0.000 n=50+50) GetStripedOffsets/length100,seed777-4 1.97ms ±21% 1.89ms ±18% -3.98% (p=0.046 n=50+50) GetStripedOffsetsEven/length10-4 1.06µs ± 2% 2.67µs ± 1% +152.75% (p=0.000 n=44+43) GetStripedOffsetsEven/length100-4 14.3µs ± 1% 62.4µs ± 3% +337.62% (p=0.000 n=42+43) GetStripedOffsetsEven/length1000-4 370µs ± 1% 4807µs ± 1% +1198.18% (p=0.000 n=44+45) name old alloc/op new alloc/op delta GetStripedOffsets/length10,seed777-4 766B ± 2% 2144B ±17% +180.06% (p=0.000 n=50+50) GetStripedOffsets/length100,seed777-4 7.90kB ± 3% 103.93kB ±11% +1216.44% (p=0.000 n=50+50) GetStripedOffsetsEven/length10-4 576B ± 0% 1392B ± 0% +141.67% (p=0.000 n=50+50) GetStripedOffsetsEven/length100-4 5.90kB ± 0% 9.55kB ± 0% +61.79% (p=0.000 n=50+50) GetStripedOffsetsEven/length1000-4 47.0kB ± 0% 82.5kB ± 0% +75.59% (p=0.000 n=50+50) name old allocs/op new allocs/op delta GetStripedOffsets/length10,seed777-4 15.0 ± 0% 36.6 ±15% +144.00% (p=0.000 n=50+50) GetStripedOffsets/length100,seed777-4 104 ± 5% 223 ± 7% +113.13% (p=0.000 n=50+49) GetStripedOffsetsEven/length10-4 12.0 ± 0% 39.0 ± 0% +225.00% (p=0.000 n=50+50) GetStripedOffsetsEven/length100-4 72.0 ± 0% 225.0 ± 0% +212.50% (p=0.000 n=50+50) GetStripedOffsetsEven/length1000-4 472 ± 0% 2031 ± 0% +330.30% (p=0.000 n=50+50)

Resolves #1332 (comment)

With the new progress bars this logging is not needed, though we might bring it back once something like `--ui-mode=log` is implemented. Resolves #1332 (review)

This allows metric processing to still occur, even after the script run has completed. In practice, this allows you to run k6 with the --linger --no-teardown flags, and execute the teardown() function manually through the REST API, after the main test run has completed. This also fixes #1369 - now a second Ctrl+C will _always_ abort k6, albeit in a very abrupt way. On the other hand, the first Ctrl+C would be more graceful than it currently is, since it will now allow teardown() to be executed.

The previous implementation worked basically as follows: A list of changes to the arrival rate is generated where there is a minimum time between these changes (currently 250ms). This means that for any ramp-up/down there is a step every 250ms (more or less). After this is generated a goroutine will read that list and send the change on a channel at the appropriate time. During ramp-up/down this is every 250ms (more or less). Another goroutine will be receiving those changes and resetting a timer to the new value. And here is where the problem lies: If the arrival rate is more then 1 iteration each 250ms this means that it will never trigger the start of a VU. The extreme example is having ramp-up to 4 iterations per second - this is exactly 1 iteration each 250ms, which means that for the whole duration up to end of the ramp-up there will be zero iterations started. In order to completely remove this, I went the step further. The way we separate the interval in small pieces reminded me of integrals and is one of the very easy cases for using integrals. So I just calculate the integral of the function that is the number of VUs over time. The answer is how many iterations need to be done there, so if I reverse this and instead calculate for how much time I will get 1 I get when the first iteration should start. I can do that for any iteration number and if there is no result then obviously we can get that :D. This also has the awesome side effect that if we split the execution in 10 we only need to calculate 1/10th of the integrals on each instance.

Refactor the Engine to process metrics independently from the test Run

This cleans up how context was being handled for purposes of interruption, and introduces a VU activation method that also handles de-activation (i.e. returning the VU to the pool) via a callback passed during execution. See #1283

This is a gotcha of the API that could easily leak goroutines... I'm hoping this will resolve all timeout failures in CI.

Resolves #1368 (comment)

This avoids panics with concurrent RunOnce calls. It essentially brings back a2e1c6f. Resolves #1368 (comment)

This is not good, for several reasons: - "Active VUs" are tracked in three different places: the activeVUs WG used for synchronizing VUs with the executor's Run(), the activeVUsCount used for progress/UI, and the global active VUs count in ExecutionState shared by all executors. Ideally there should be a single API that unifies this and preferably doesn't allow direct access to ExecutionState. - getVU increments the local active VU count (and in contrast those must be decremented in returnVU), even though VUs aren't technically "activated" until vuHandle.start() is called. Fixing this would involve changes to vuHandle to maybe also handle an additional activateVU lambda. - This change moves the global ExecutionState VU count handling to handleNewScheduledVUs(), mainly so that tests like TestVariableLoopingVUsRampDownNoWobble can access it, but this is not a good reason, and the split active VU tracking will likely cause weird issues when run with other executors. The refactor in point 1 above would likely help here.

This aligns it more with how this is done in regular execution. Resolves #1368 (comment)

This ensures executors wait for all VU deactivation goroutines to complete. Resolves: - #1368 (comment) - #1368 (comment) - #1368 (comment)

Resolves: - #1368 (comment) - #1368 (comment)

See #1368 (comment)

This does the same changes as the commit before for the constant-arrival-rate executor, to avoid any potential hanging, since both executors behave similarly.

Resolves #1368 (comment) but unresolves #1368 (comment) :)

See #1408

Merge master into new-schedulers

Tests that share a VU like TestVURunInterruptDoesntPanic need to access the same mutex instance, otherwise it panics while reading setupData. This could be fixed in the test itself, but protecting against panics should be transparent to user code.

This is still crappy, but it seems to produce base commits more reliably.

Previously the variable arrival rate instead of stopping VUs right away after they need to stopped them on the next step down. This is also not how the previous stages worked and is not how it was designed to work in the first place so it needed to be fixed. The speed up comes from the fact that we now skip some calculations if the test is not ran with a full execution segment. Unfortunately this is slower for the full execution segment as there we still do all the calculations but now we additionally do more stuff, maybe some more optimizations can be done name old time/op new time/op delta VarriableArrivalRateGetRawExecutionSteps/seq:;segment:/normal-8 461µs ± 1% 571µs ± 3% +23.70% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:/rollercoaster-8 5.31ms ± 2% 6.19ms ± 2% +16.69% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:0:1/normal-8 463µs ± 2% 569µs ± 2% +22.93% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:0:1/rollercoaster-8 5.28ms ± 1% 6.21ms ± 2% +17.71% (p=0.000 n=19+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.3,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.3/normal-8 311µs ± 2% 163µs ± 2% -47.38% (p=0.000 n=19+19) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.3,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.3/rollercoaster-8 4.22ms ± 2% 2.10ms ± 2% -50.13% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.1/normal-8 209µs ± 4% 44µs ± 3% -78.90% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.1/rollercoaster-8 2.82ms ± 3% 0.68ms ± 2% -75.98% (p=0.000 n=20+19) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2/5:4/5/normal-8 354µs ± 3% 217µs ± 2% -38.76% (p=0.000 n=19+18) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2/5:4/5/rollercoaster-8 4.70ms ± 4% 2.71ms ± 2% -42.24% (p=0.000 n=20+19) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2235/5213:4/5/normal-8 9.77ms ± 3% 0.21ms ± 2% -97.90% (p=0.000 n=19+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2235/5213:4/5/rollercoaster-8 60.4ms ± 3% 2.5ms ± 2% -95.86% (p=0.000 n=20+20) name old alloc/op new alloc/op delta VarriableArrivalRateGetRawExecutionSteps/seq:;segment:/normal-8 1.07MB ± 0% 1.07MB ± 0% ~ (all equal) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:/rollercoaster-8 14.6MB ± 0% 14.6MB ± 0% ~ (p=0.121 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:0:1/normal-8 1.07MB ± 0% 1.07MB ± 0% +0.01% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:0:1/rollercoaster-8 14.6MB ± 0% 14.6MB ± 0% +0.00% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.3,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.3/normal-8 254kB ± 0% 254kB ± 0% +0.04% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.3,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.3/rollercoaster-8 4.62MB ± 0% 4.62MB ± 0% +0.00% (p=0.000 n=20+19) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.1/normal-8 49.1kB ± 0% 49.3kB ± 0% +0.24% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.1/rollercoaster-8 1.38MB ± 0% 1.38MB ± 0% +0.01% (p=0.000 n=19+19) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2/5:4/5/normal-8 352kB ± 0% 352kB ± 0% +0.04% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2/5:4/5/rollercoaster-8 5.83MB ± 0% 5.83MB ± 0% +0.00% (p=0.000 n=19+17) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2235/5213:4/5/normal-8 352kB ± 0% 352kB ± 0% +0.04% (p=0.000 n=16+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2235/5213:4/5/rollercoaster-8 5.83MB ± 0% 5.83MB ± 0% +0.00% (p=0.000 n=20+19) name old allocs/op new allocs/op delta VarriableArrivalRateGetRawExecutionSteps/seq:;segment:/normal-8 20.0 ± 0% 20.0 ± 0% ~ (all equal) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:/rollercoaster-8 31.0 ± 0% 31.0 ± 0% ~ (all equal) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:0:1/normal-8 20.0 ± 0% 22.0 ± 0% +10.00% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:0:1/rollercoaster-8 31.0 ± 0% 33.0 ± 0% +6.45% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.3,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.3/normal-8 15.0 ± 0% 19.0 ± 0% +26.67% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.3,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.3/rollercoaster-8 26.0 ± 0% 30.0 ± 0% +15.38% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.1/normal-8 11.0 ± 0% 16.0 ± 0% +45.45% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:0,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1;segment:0:0.1/rollercoaster-8 21.0 ± 0% 26.0 ± 0% +23.81% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2/5:4/5/normal-8 16.0 ± 0% 19.0 ± 0% +18.75% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2/5:4/5/rollercoaster-8 27.0 ± 0% 30.0 ± 0% +11.11% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2235/5213:4/5/normal-8 16.0 ± 0% 19.0 ± 0% +18.75% (p=0.000 n=20+20) VarriableArrivalRateGetRawExecutionSteps/seq:;segment:2235/5213:4/5/rollercoaster-8 27.0 ± 0% 30.0 ± 0% +11.11% (p=0.000 n=20+20)

fixes #1296

…#1420) Co-Authored-By: Ivan Mirić <ivan@loadimpact.com>

We should be at 10 VUs at exactly t=3s, so the additional 100ms of head start is enough.

Previously what was happening that the context could timeout by the time RunOnce is called which will lead to it seeing that and exiting with the context error (timeout in this case). This is easily fixable by creating the context just before it is used. Which also makes it possible to decrease the context timeout significantly, as it now doesn't need to last newVU for example.

This replicates the approach used for js.ActiveVU in 4892443.

Unfortunately because of the way the ExecutorConfig interface is designed I can't just cache some of the results which will result in some probably unneeded amount of calculation. This will need either a change to the interface or for ExecutionTuple to cache the results of GetNewExecutionTupleBasedOnValue, but I find it unlikely this to be noticeable outside of extreme examples closes #1308

Refactor VU context handling, introduce VU activation

See #1300

This leaves executor init before VU init, but moves the config validation to a more suitable place before the engine/ExecutionScheduler is initialized. It now also properly reports errors from more than one executor. Resolves #1428 (comment)

Not sure if this is an improvement honestly, but I didn't find a way to set a default value for null.String.

This now also grabs all exported functions, including setup/teardown. Partially resolves: - #1428 (comment) - #1428 (comment)

Resolves #1428 (comment)

This was done in e693715 to ensure exec validation would fail before VUs are initialized, but now that this validation is done much earlier, this is no longer needed. Resolves #1428 (comment)

The minor optimization wasn't worth the messiness. Resolves #1428 (comment)

Resolves #1428 (comment)

This reverts commit 25a26ab. Concurrent calls to getVUActivationParams would cause race conditions when reading from BaseConfig and several tests would fail, so this needs to be done only once per executor, and we need this RunContext overriding after all.

This avoids having to read state.Options in some cases, as that should be done only once in runFn. Resolves #1428 (comment)

Resolves #1428 (comment)

This applies the same fixes as eb13303 and d01e2c1 for the VLV executor, to ensure activeVUsWG.Wait() is called last, after the context has been cancelled. It resolves some race conditions exhibited by the TestExecutionSchedulerRun* tests (e.g. [1]). [1]: https://circleci.com/gh/loadimpact/k6/10139

This cleans up the interfaces and makes it possible to re-use the heavy calculations for a segment sequence.

This would previously fail without the fixes in #1453.

…-options Add support for exec/env/tags executor options

this should again lower the amount of time test take for close to zero additional scripting.

* Process metrics and thresholds after test run finishes This is a quick and dirty fix for #1434, though as I mention in that issue, the proper solution would be rewriting that code from scratch... Co-authored-by: Ivan Mirić <ivan@loadimpact.com>

Previously (since e693715) running a TAR file would overwrite the options set in the metadata.json with the script's exported options. This is a hacky fix, but the alternatives weren't much cleaner.

Fix racy tests

The problem was that pausing used gracefulStop which in turns wait for the VU used by handle to be returned. The fix is to have another context that is used for the actual runContext of the VU so we can cancel it when we get gracefully stopped. I tried to simplify (and speed up) the looping by only going through all the channels and context stuff if there was a change, otherwise we use a int32 and some atomic.LoadInt32 to see that "there is no change" and we directly start a new iteration. Additionally now the getVU error is propagetted by the vu handle's start, which is probably badly handled in this commit. Also the function that does the iteration now returns whether it was interrupted mostly to help with faster interruption of the fast looping. This might be reverted in a future commit, if the speed up isn't wanted. Unfortunately in order to support returning the VU and not returning it and still gettign the new VU but still to get start to actually return the error from getVU it took way more code then was anticipated ... The speed up is "insignficant" too, by my proffiling we were spending around 150-250ms (of 30s) in the mutex locking/channel reading now we spend 10ms(of 30s) in loading that int32. So 15-25x, but this is some sub percentage time and this is for an empty bodied `default` function. More benchmarks to come :D. There is also a not so great benchmark :D name iterations/ns VUHandleIterations-8 0.04 ± 1% so around 40ns per iteration

Increase time interval between log message to 200 milliseconds Remove Writing JSON metrics message Add if statement output log based on no of count

This handles the executor configuration parts of #1425, without actually changing the Go type names or structure yet.

Also fix VLV not respecting gracefulStop since 270fd91, add test for it and try to make some other VLV tests more stable. The original code (pre 270fd91) did go through all the raw steps (ramp up/down) and the graceful stop ones concurrently and when the raw steps ended it will return from Run, but will start a goroutine to go through the remainign graceful stop ones. The most important of which ( at least in my current understanding) being the last one which is the actuall gracefulStop end which will make all VUs stop. The reason why this actually worked is that it also waiting on all activeVUs to have ended being active, being returned in the new terminology, before it actually cancels the context for all of them. So if the VUs manage to end iterations in this time the executor will end earlier if not the gracefuStop will make them. 270fd91 broke the returning of VUs which lead to the executor never returning and moving the cancel "before" the waiting for activeVUs fixed that at the cost of gracefulStop not being taken into account, but with no tests, nobody noticed. Here I basically revert that especially because vuHandle now returns VUs when stopped. fixes #1473 Co-authored-by: na-- <n@andreev.sh>

this is ... mostly a complete rewrite of vuHandle now using an atomically updated state to work as a state machine. There is still a fast path which provides all the speed, but now it also always returns any VU it has got and doesn't return it in cases where this isn't required - there was a start after a gracefulStop, but before it actually stopped. closes #1492

Fix benchmarks

Previous to this past running k6 compiled with the race detector and ws code will most definetely leak enough goroutines in 10 seconds that it will stop because of the 8k limit ... After this it seems to not leak anymore :confetti:

Update ws lib and goroutine leak fixes

Closes #1511

This replicates more closely what the local ExecutionScheduler does, and is needed for correct assertions in externally-controlled tests.

This tags all metrics emitted in the main "exec" function with a "scenario" tag set to the scenario name or "default" if no custom scenarios were defined. It can be disabled with the `--system-tags` option. There's no issue for this specific feature, but see #796 and #1300.

Update goja

Resolves #1517 (comment)

This took way longer then I anticipated mostly because of ... how strange some things work. The basic idea came from that for each iteration we constantly remake the iterations which looked (and probably is) the lowest hanging fruit in k6 about creating too much objects. Unfortunately because of how .. tags work and that iteration is a tag I need to still copy the tags for GetTrail .. (it gets copied either way for other metrics). When running with a empty body did this change the amount of cpu taken by scanobject and decreased it from 7.98s to 5.81s (while most other not GC related had difference withing 0.3s). This is very small step ... having tags being immutable so we don't have to constantly copy them will likely be much more significant or if we can reduce the calls to runtime.nanotime which are literally now the top CPU usage with empty iterations and are the top CPU usage for simple scripts even before that :D.

Fix externally-controlled maxVUs scaling

…ecutors (#1525) fixes #1317

This make it so that if an unplannedVU needs to be started we wait for ANY free VU instead of only for that unplannedVU to start the next iteration. Also puts in place some guards against initing multiple unplannedVUs

…edVUs Fix ramping arrival rate unplanned vus

Closes #1488

…ng Run

In order to reuse SumStagesDuration and move it to lib, I had to remove the duplicate executor.Stage definition, and reuse the one in lib, which might be cleaner anyway.
