I think the performance under load on Mac OS X isn't so bad. But it
does use a lot of CPU on idle, for whatever reason.
There are somethings that can be done to make things run better on
Mac OS X. For example, on Mac OS X and Windows, Pd uses double-
precision math functions while Pd only uses single-precision floats.
If Pd used the single-precision functions, then things would probably
use a bit less CPU.
