I've noticed exactly the same behaviour on Mac, it's a very annoying  
problem. Just having the sound device open seems to consume an  
inordinate amount of CPU cycles already. From what I've seen, it  
actually seems to be a PortAudio issue. I already went on their  
mailinglist to discuss the issue, but I didn't pursue the matter.
