pd and clock cycles

[Michal Seta]

Hi all,

Funny thing I noticed.

When I run pd with the default settings (-r 44100 -ada) no gem
(still.....) it eats up about 50% of the cpu cycles.  Just when it's idle,
no patches open, audio off.

In the case of the same sampling rate but running in -dac mode it takes
about 1% when having something like one osc~.

I can run it fine in the -ada mode at -r 22050.  Even a complex patch
doesn't take much cpu (well, within reason).


Any ideas about this behaviour?
