[Question] Meaning of CPU Speed / Events per second? #503

Open

I'm trying to compare the CPU speed of two servers with sysbench cpu run (see attached images with results).

Server 1: CPU Speed/events per second 337.06
Server 2: CPU Speed/events per second 3682.68

But both servers have a similar total time around 10s.

Questions are:

Are both CPUs equivalent in speed because they end up having the same total time?
Is server 2 faster because it sends more "events" per second?
What's the meaning of these "events"?

Thanks!
Antonio

Ah, it seems this previous answer explains how to interpret these results:

you either limit the total time (default) and then the number of events per second is the performance indicator).
Or you either limit the number of events per second (and then the total time is the performance indicator).
In any case the "latency" is a good performance indicator.

Maybe we want a document explaining these results? If so I can do a PR, for instance.
