Specifically, what CPU / audio hardware you have, if you're using any non-defauly PA settings, what your buffer size / sample rate is in JACK, what applications you're running that interface with the sound servers (e.g. pavucontrol, carla). I have a fairly complex setup that routes sounds from PA to JACK and back to PA, and the PA server only consumes ~5% of one CPU core (on an i7-6600U laptop). Running pavucontrol can cause that number to rise, though, since each sound source / sink has an audio stream to drive the VU meter. --Sean
