If you're on Windows and you have Visual C++ 2010/2011, there's some project files at https://github.com/Juntalis/PyOptiPng that you can compile that use SSE2 optimized settings when compiled under Release configuration. If you don't have the compiler yourself, I can send you the resulting executable. (Granted you're on an x86 computer. Unfortunately, that's what I'm limited to right now)

If you're on Linux/Mac OSX, you should be able to compile it yourself with -msse2 in your CFLAGS.
