You're right, "pd" is taking all the cpu, Pd-0.43.4-extended-20121030 is 
0%. From what I see with shark, the cpu is mostly used by a mach kernel 
function : "ml_set_interrupts_enabled" and by dsp function from 
"DspFuncLib" that all looks like usual effect ( processIIR, equalizer, 
multibandcompressor, ...). I can send the report off list if you like.

Still how can you explain the cpu decrease when the window is moving?

> In the pd source tarball is a folder called 'portaudio'.  Delete it, then download the version you want to try from http://portaudio.com.  When you unzip it, you'll see a folder called 'portaudio', but that in your pd source, so its like pd/portaudio/ as in pd/portaudio/src

ok, I don't have much time now, but I'll try as soon as I can.
