Dear all,
So, I've just upgraded to Ubuntu HH, and I'm using the Linux
2.6.24-17-rt #1 SMP PREEMPT RT kernel on a toshiba laptop with dual
core 2.6 GHz processors and 2G of ram, and an intel HDA
I have compiled Ardour 2.4.1 from source with FREESOUND=1 as my only
option. My first problem is that it's using 74% of my CPU just sitting
there. [Anyone else find this?]
I've checked that my system corresponds to this page
http://tapas.affenbande.org/wordpress/?page_id=40 (as this was how I
used to have it set up) and it corresponds, but I'm getting 5% CPU
usage from Jack just sitting doing nothing.
Anyone got any ideas?
The 5% could be normal if you have very low latency settings, since the
lower the latency the higher the cpu usage, even when idle.
Ardour chewing 74% cpu on the other hand is far too much, it should use
nearly nothing. I haven't compiled 2.4.1, Version 2.3 that ships with
hardy appears to work fine here.
Best Regards
Philipp
