Extra cores should give better performance for a multitasking operating
system in general. But it doesn't necessarily give you better
performance for each individual task you want to do. Pd is
event loop for every single modern web browser out there. So the trend
of chopping up cpus into little bits effects a lot more than just Pd.
I imagine it would run at 2.6, but I don't know what the Mac interface
is for setting that.
I've read on this list that there are issues with using pd~ together
with Gem. It was suggested instead to run two instances of Pd, one for
Gem and the other for audio. You can communicate between the two using
a netsend/netreceive pair over local host.
