This laptop is x86_64 and has 1GB RAM. Up to and including FC6 this was fine and it hardly ever reached the limit, performance was always good. Starting with Fedora 7, and really much more obvious now with Fedora 8 I'm finding it's using far too much RAM and regularly hitting swap very badly. Performance has suffered considerably. I've been thinking of shelling out some cash on 2x 1GB SODIMMs, but unfortunately these DDR1 versions are very expensive. As an example, there's two users logged in at the moment, I'm running evolution, galeon, and an xterm. The other login has nothing extra running, it's just gnome. Here is the output of free: total used free shared buffers cached Mem: 1027656 1008372 19284 0 43276 135564 -/+ buffers/cache: 829532 198124 Swap: 1048568 48 1048520 Yes, 810MB of memory really in use. I'm running gdesklets but not running other new stuff such as NetworkManager, yum applets, compiz etc. This level of memory use feels quite excessive. Unfortunately determining where RAM has gone is still somewhat difficult on Linux. It would be great to have Matt Mackall's patches in, or Exmap available. The best I've found without having to patch the kernel is: http://www.pixelbeat.org/scripts/ps_mem.py Running this as root, the biggest culprits are: Private + Shared = RAM used Program 3.4 MiB + 7.6 MiB = 11.0 MiB notification-area-applet (2) 10.6 MiB + 1.8 MiB = 12.4 MiB gconfd-2 (2) 11.8 MiB + 1.3 MiB = 13.1 MiB bbackupd 4.4 MiB + 9.4 MiB = 13.8 MiB evolution-alarm-notify (2) 5.3 MiB + 8.9 MiB = 14.2 MiB mail-notification (2) 4.7 MiB + 9.7 MiB = 14.4 MiB metacity (2) 8.2 MiB + 7.5 MiB = 15.7 MiB gnome-power-manager (2) 4.1 MiB + 11.6 MiB = 15.7 MiB padevchooser 15.3 MiB + 556.0 KiB = 15.8 MiB restorecond 14.5 MiB + 1.6 MiB = 16.1 MiB xterm 6.0 MiB + 10.3 MiB = 16.3 MiB notification-daemon (2) 6.0 MiB + 11.7 MiB = 17.7 MiB wnck-applet (2) 6.1 MiB + 11.7 MiB = 17.8 MiB clock-applet (2) 8.8 MiB + 12.5 MiB = 21.3 MiB mixer_applet2 (2) 11.0 MiB + 13.4 MiB = 24.5 MiB gnome-panel (2) 13.9 MiB + 15.7 MiB = 29.7 MiB /usr/libexec/re 23.0 MiB + 9.0 MiB = 31.9 MiB gnome-settings-daemon (2) 21.5 MiB + 15.8 MiB = 37.3 MiB nautilus (2) 23.9 MiB + 18.0 MiB = 41.9 MiB evolution 30.3 MiB + 13.2 MiB = 43.5 MiB /usr/bin/sealer (2) 34.7 MiB + 14.7 MiB = 49.5 MiB deskbar-applet 43.1 MiB + 8.5 MiB = 51.7 MiB beagled (2) 50.8 MiB + 10.4 MiB = 61.2 MiB Xorg (2) 80.2 MiB + 12.7 MiB = 92.9 MiB python (4) 80.6 MiB + 16.1 MiB = 96.7 MiB galeon Galeon seems a bit heavy at 80M for a few tabs, but mozilla based browers aren't renowned for being light. What really stands out for me here is deskbar-applet, how can that be using all that memory? Also sealert and beagled are very excessive. To verify the numbers above I killed these tasks off and checked the reduction in used space (- buffers). The expectation is to see the private memory returned, and that's almost exactly what I got: 1 x deskbar-applet 35MB 2 x beagled 44MB 2 x sealert 32MB Over 100MB returned by removing a few almost never used programs, but I'm still at 698MB, which is still way too much. Looking back up that list there's many other things that are using too much memory. How does a clock applet use over 6MB of private memory?
