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

<div>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.</div>

</div>
<div>After much testing, it seems to be only the Ubuntu Unity
Dash getting slower, and only after a crash of Ardour3... </div>

Maybe it helps when you clean up the cache after Ardour crashes?<br>
