carmen, judging from the rest of your post, CPU usage was the main
issue.

this is actually not a consequence of the JACK sink directly, but the
appalling unoptimized resampling code in gstreamer. if you connect the
JACK sink up to a stream that is already at the JACK sample rate, i have
found you see the expected (low) CPU utilization.

the gstreamer guys know about this, but there is nobody available or
with the know-how to speed it up. libsamplerate is not an option,
apparently, because of the license :((
