The new stack has I believe lowered the CPU usage a little. Compiling with optimisations also helps. I don't believe there's a lot of scope to improve on this without major changes to FFADO's lower level functionality. In time I expect the in-kernel streaming engines to help in this regard, and for that reason I don't think there's a lot of point in keeping this ticket open.
