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

boolean.zip
it is input file and source file , @alecjacobson

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!

老哥，这个问题我没解决，用其他的库了

原来也是中国人的哈哈哈；哪你用的是什么库，这个是不是框架问题？能不能加一个联系方式沟通一下？邮箱 13624491832@163.com,企鹅 1139627754

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

[alecjacobson]

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? For 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.
