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
Thanks for the suggestions, I'll try that out next time.
@David: In Ubuntu 12.10, Unity 2D doesn't exist anymore. And thanks for
the suggestion, but I actually doesn't want to drop Unity for XFCE - I
really like the look and feel of Unity... But that's a discussion for
another time :)
Very true. My wife and I both hate the Unity UI with a passion.
