Hello everyone,
I have been running into an issue over the past couple of months with
Ardour and Ubuntu.
When using Ardour intensively in Ubuntu for a couple of hours (switching
between songs, doing recordings and mixing, etc), Ubuntu slows down
dramatically. By Ubuntu I assume the couple Unity/Compiz - Alt+Tab takes
seconds to appear and react to commands, the Ubuntu Dash becomes horribly
slow and the only thing I can do is reboot the machine. In the mean time,
Ardour and other software are still running pretty much ok. Checking the
processes, Compiz and X are the ones using the processor a lot.
This doesn't seem to happen with any other software but Ardour (I'm using
Hydrogen or SuperCollider a lot), and I did a few tests with Gnome3, there
it seems to be ok.
My setup is as follows:
- Ardour3 Beta5
- Ubuntu 12.10 64bit
- Using the Radeon open driver (FGLRX creates a lot of xruns)
Now, I am not trying to start a conversation "Should I use Compiz when
playing music" or "Ubuntu is crap, what else should I use?" :)
I like Ubuntu, I like Unity and I like Ardour3!
I am just checking if other people are experiencing the same issue, if
there is a solution to this problem, what additional testing I should do or
what additional information I should provide.
Finally, if it is a bug, where should it be reported? Is this an Ardour bug
as it seems only Ardour is making this problem happen, or is it an
Ubuntu/Unity bug as it is the application actually slowing down?
Thanks in advance for the help!

Wonder if the CPU frequency scaling is causing this issue. I had an
issue on a Dell machine at work where the box would run really slowly
if it got the slightest bit hot from being pushed too hard (usually
doing big Subversion commits or running sipp against a remote server).
The governor would take it down to the lowest frequency level to help
the machine cool down. This would even happen if I turned on the
performance governor. It wasn't a Linux issue at all, because people
who had the same hardware had the same problem on Windows.

The thing is, the CPU never really goes over 40% usage, the rest of the
machine is still working ok, only Unity/Compix are getting much slower.
After much testing, it seems to be only the Ubuntu Unity Dash getting
slower, and only after a crash of Ardour3...

Using Unity 2D or 3D? 2D is supposed to use less.
My suggestion: drop Unity, use XFCE instead.

Maybe it helps when you clean up the cache after Ardour crashes?
sudo sync; echo 3 | sudo tee /proc/sys/vm/drop_caches

I removed Compiz from an AV Linux install, because the performance was
bad. Just my experience ;).
