sorry if i missed the announcement, but where can i find this [pd~] object and some documentation? cheers
Hi Jon, i think it comes with the latest pd extended, at least i didn't explicitly install it and i do have it, so... gr, Tim

the average cpu load won't tell you a lot, since the cpu speed is usually not constant, but may be modulated (adding some latency hotspots). in general, i'd recommend to disable frequency scaling, turbo mode (for
nehalem
cpus) and smt, since it may confuse numbers and can increase the thread wakeup latency significantly, if you want to use a machine for
low-latency
real-time audio applications.
so, still plenty of overhead on the 4th core, but it doesn't seem to be used.
from my understanding, you should split your path into 4 pieces of equal load, using 3 pd~ objects, if you want to optimize it for a quad-core
cpu.
