OK, just tried my Edirol FA-66 firewire interface. CPU does indeed drop to 12%.
Still that's a ridiculous overhead for simply talking to the audio hardware.
A profile would show that the DSP functions are no longer taking CPU time. The remaining 10% is the blocking.
Does that mean that Mathieu was wrong earlier about the PABLIO interface not causing any significant overhead?
I don't know much about PortAudio and PABLIO. The blocking call probably does come from how Pd uses PA.
