[PD-ot] how low (latency) can you go?

[Hans-Christoph Steiner]

Apple puts good audio hardware in their laptops.  I can get 14ms of  
latency on Mac OS X with Pd without really trying (I just set it to  
14ms).  I can get down to 11ms if I don't mind clicks when I operate  
the menus and switch to other applications.

I think that if you really want to get down to something like 2-3ms,  
then you'll have to work at it, and you'll probably be better of with  
a Debian-based system or maybe PlanetCCRMA.
