But in the book it was stated that csound looks for Portaudio before anything else, so for testing I installed Portautio from source and re-compiled csound. I'm bad at benchmarking but I'm curious to know if callback portaudio would be a good realtime solution as linux user, and furthermore would it make sense to mix it with the RT-Kernel. I already get very low latency with high priority jack connection so maybe using portaudio would be slower than the results possible there.

--format=float has no effect on the internals of Csound computations.
--float is for audio file output. In theory it could also apply to
real-time audio drivers but the effect should be undetectable and
would in any case depend upon the internals of the driver.

Mike
