Anybody Still Using a Pentium 3?

on Sat, Oct 17, 2009 in development

I’m going to assume that few users are still using anything older than a Pentium 4/Celeron ( which were released in 2000) and make a few changes to MeshCAM. Starting with the P4, Intel/AMD made the SSE2 instructions available. Enabling them in Visual Studio gives MeshCAM a 6% boost in my test case without doing anything else. I expect that I can do better if I make changes to target these new instructions more explicitly.

Between this and some other changes MeshCAM is running about 15-20% faster than the last release.

UPDATE: I just made another small change and it’s now about 44% faster in my benchmark.
