Although peter huwe said in comment #25 that he sees degradation when swap is not in use, I suspect that the degradation tends to happen on my system when swap starts being used, almost as if compiz/unity is having its data swapped out to disk which then slows it down. Typically on my system some process will use a ton of memory (firefox, Netbeans) that causes the system to hit swap, and afterwards the windows stagger around when I move them instead of moving smoothly.
It *is* a different issue from the slowdown I used to see in glxspheres, because I've seen glxspheres perform normally when the windows are staggering around. One nice observation I have is that the versions of unity/compiz from Daniel's PPA seem to recover by themselves from the degradation a while after I close down the offending process using lots of memory (although not immediately), which is far better than before. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/888039 Title: Gradual degradation in desktop performance.
