I use Ubuntu GNOME without Unity and face same problem (fresh boot, opening several browser tabs - chrome, opera, atom and system starts using swap and freeze UI in 30 minutes of browsing, 4Gb RAM + 4Gb Swap ). It was not so irritating before upgrade from 15.10.
Swappiness set to 5 (but didn't help much) So I believe it may not be connected with Unity, but would support idea in post #30 about problems with memory management -- 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/unity/+bug/1572801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
