--- Comment #13 from Alexander E. Patrakov patrakov@gmail.com 2012-05-13 11:38:52 CDT --- Yes, it makes sense. SW3 creates one buffer at 44100 Hz and up to 15 buffers at 22050 Hz, and that's enough to overload your CPU. I think that on your CPU Darwinia 2 Demo is also affected (that's what I am benchmarking with), as it creates 32 buffers at 22050 Hz.
