Daniel, the performance drop with activated Unity is quite large, so my eyes can catch the change in performance easily.
Animations, moving wobbly windows - all is much smoother without Unity. But it is also possible to measure the performance drop with the Compiz benchmark tool: You just have to take a large window and move it around wildly, because otherwise Compiz Standalone gets to sleep and shows just around 3-6 fps here, which also shows that the damage detection seems to work, while Unity always renders more than 20fps, even if your screen content almost does not change. If I move a big window around with Unity activated (dual-screen), the benchmark never shows more than 28 fps. With deactivated unityshell I can get it to show around 40-60 fps, which reflects my observation. om26er, this bug already was reported before (bug 988079), but it was marked as fixed, which I cannot confirm here, so I decided to file a new bug. ** Changed in: unity Status: Incomplete => New ** Changed in: unity (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049392 Title: Unityshell slows down Compiz massively To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1049392/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
