Can anyone currently using PD for low latency audio on OSX follow up on 

I'd like to know if anyone has done any "speed tests" between Linux with 
ALSA and with JACK compared to OSX with Portaudio and with JACK. How 
much latency should I expect to lose from my HDSP, for example, if I run 
the same patches I normally use under Linux/JACK on OSX/Portaudio or 

Also if anyone has had difficulty/success compiling PD with JACK support 
on OSX, either Main or Devel branch.
