I have started experiencing this issue after latest kernel update. As many discovered that memory leak in evolution-data-server is one of the culprit. But even after killing all eds services the memory usage still at 800mb+ unlike trusty (500~600mb). So it is not the only reason.
Btw, memory leak has been fixed in evolution-data-server >= 3.20, although I don't which commit exactly does that. We can not use 3.20 on 16.04, but it is possible to cherry-pick those patches (I don't think upstream will ever do that) which fixes the leak. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572801 Title: Ubuntu 16.04 Unity desktop uses much more ram than Ubuntu 15.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1572801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
