Wow, you're right!  Mine was set to "automatic".  I now get the same 
results as you do.

I am utterly shocked that OSX's power saving options are that 
inefficient.  Surely if the OS detects that there's high CPU use, it 
should kick in to "highest" and leave it there for a while, right?  62 
-> 48 is a pretty significant gap in performance.

No need; sorry if my initial email seemed a bit harsh.  I'm very 
adverse to criticizing open-source projects -- I mean, I haven't paid 
anything for it, it's a free -- and even better than that, it's Free 
(speech).  It's true that I'm a little disappointed, but that's just 
because I'm so excited to have an audio programming language.  I mean, 
a _real_, text-based, language.  I hate having to use a mouse, so pd or 
Max/MSP is a non-starter for me.  If ChucK wasn't so awesome, I 
wouldn't be raising this question.  :)
