There's not enough information to replicate this issue. What's the program you're referring to?

I also have this problem! For the example of the 405 ARAP tutorial on MAC, I am in libigl-example-project
Why is the down run so slow? But the official website example runs fast? I only changed the file directory. TUTORIAL_ SHARED_ PATH "/decided-knight.off" is changed to "/Users/xxx/libigl-example-project/decided-knight.off", which is a special card! The information of the computer is as follows!

@alecjacobson Hi, am I providing enough data messages now? Is the simd not triggered? Or is it something that caused it?

Could you confirm that you're compiling in release mode?

You could use make VERBOSE=1 and verify that you see -DNDEBUG and -O3

Switching to release performs better in vscode,

and directly making a running program will get stuck compared to vscode. Is there a problem with the number of iterations of this algorithm? imageFor example, if I change the number of iterations in the tutorial to 4 or 5, it will be very smooth. Is it an algorithmic problem or is the SIMD of the framework not started? Generally speaking, the original tutorial setting of 100 is for normal use.
