JACK adds no latency but it adds a bit more CPU usage. Nothing too
much to be noticed on fast CPUs but if you are very limited with
resources it is very noticable (on my old EEE704 I can run Pianoteq
with alsa and using Rhody patch almost normally but with JACK it won't
do. On my Core2Duo I can't even see difference in CPU usage between
JACK and alsa).

Cheers!
