Hello,
I have a routine that is slooooow. I would like to try and speed it up, but
I don't know where to focus my efforts because I don't know what part of the
process is taking all the time. So, is there a way to see how long each
section takes? I tried using systime at the beginning of each section, but
it only has resolution in seconds! If it matters, I'm on a Windows system.
Thank you,
Sean

I think what you want is the PROFILER command.
That will show you what is taking all the time.
Cheers,
David

windows machines don't have high precession (or at least they
didn't use to). I doubt you can get past 10ms.
I suggest taking the components and looping a few thousand times.
Cheers,
