--- Comment #16 from Alexander E. Patrakov patrakov@gmail.com 2012-05-13 12:30:37 CDT --- According to my testing with Darwinia Demo,
1) Something has changed in my system so that SSE2/3 optimizations don't have as much effect as I stated before. So more profiling is needed, and let's drop the idea until it is confirmed independently.
2) 32 streams (as used by Darwinia) is about as much as a Core 2 Duo E6420 @ 2.13 GHz (a top-class CPU from 2007) can handle with the high-quality resampler.
3) Low-quality resampler works. I only need to make the maximum high-quality buffer count a registry setting.
