for a few months now my jackd1 (0.121.3) takes on a lot of CPU, even with no clients connected.
Are there any connections like system:capture -> system:playback?
Normally JACK stays below 2% though.
If it "builds" over time, is it linear, or is it around 2% for a long time, and then builds to 90% or so?
It smells a bit of floating point denormal-processing, if its creeping up after a while of not being used. I don't know if/why JACK is performing floating ops unless there are buffers that need to be combined...
system cap1 \
system cap2 - system play1
system cap3 /
The above might explain it though - routing multiple inputs to one output.
Any idea, why this CPU-hunger might creep up? Things to look into? I'd be very grateful for hints.
The above is a "shot in the dark", but as far as I can see it could be a cause.
