I finally found that Gnome could run too @400 MHz up to some limit. Firefox makes the highest memory usage and is the limit. (no other program I use, eg Gimp, is such a bottleneck) FF seems to overuse (probably fragment) virtual memory over time. When that happens, thrashing starts. Thrashing is page swapping preventing normal use of the CPU. It can last from a few to sometimes 15 seconds or even more. If Firefox is stopped/restarted, it runs fast for some more time. (I mean restarting the same pages, of course)
In contrast, I used a 512 MB 850 MHz WITHOUT SWAP for some time. Even Firefox would run very decently in that config. Which, of course, is thrashing-free. When thrashing occurs, the mouse movements are jerky. Mouse management seems to be slowed down. So, if you want to make yourself a slow system... Boot with mem=256M on the kernel command. -- [MASTER] right click (with button release) might activate random popup-menu-item https://bugs.launchpad.net/bugs/187313 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
