Fons has discussed it in the past on the list -- here's a link:

http://lists.linuxaudio.org/pipermail/linux-audio-user/2009-December/065259.html

To quickly summarise that, the convolution engine uses multiple CPU 
cores when they're available, but the way in which it does this is 
designed for realtime operation, and can fail when running in 
freewheeling mode. From what I understand, it's likely (but not 
guaranteed!) to work on single-core systems, but on multi-core systems, 
it often (but not always) fails.

FWIW, with the performance I have on just one of my CPU cores, I'd be 
quite happy to have the convolution all run on one core if it meant that 
freewheeling mode worked reliably.

Thanks
Leigh
