Thank you guys for jogging my memory. Can you please try adding these
lines to your sysctl.conf and reboot.
vm.swappiness = 40
vm.vfs_cache_pressure = 120
I was forced down to 512 on my laptop while I am getting my 1GB chip
replaced and saw the same problem as you. Currently I am running
metacity with compositing, avant-window-navigator, epiphany, evolution,
xchat-gnome, pidgin, a couple of gnome-terminals, pida and this is my
output from free.
total used free shared buffers

Mem: 450192 444532 5660 0 884

-/+ buffers/cache: 345960 104232
Swap: 1933304 94372 1838932
I actually only have 450MB of memory because the rest is used for my IGP
video memory. Just to be consistent here is also my output from
ps_mem.py
4.5 MiB + 5.1 MiB = 9.6 MiB metacity
3.4 MiB + 7.9 MiB = 11.3 MiB avant-window-navigator
4.3 MiB + 8.1 MiB = 12.4 MiB gnome-terminal
3.6 MiB + 9.5 MiB = 13.2 MiB mixer_applet2
4.1 MiB + 9.9 MiB = 14.0 MiB gweather-applet-2
6.0 MiB + 9.6 MiB = 15.6 MiB python (2)
5.5 MiB + 10.8 MiB = 16.2 MiB xchat-gnome
6.8 MiB + 10.4 MiB = 17.2 MiB gnome-panel
8.8 MiB + 8.8 MiB = 17.6 MiB nautilus
9.1 MiB + 12.3 MiB = 21.4 MiB intlclock-applet
10.6 MiB + 11.9 MiB = 22.5 MiB pidgin
16.5 MiB + 8.7 MiB = 25.2 MiB tomboy
63.3 MiB + 14.7 MiB = 78.0 MiB epiphany
83.0 MiB + 16.6 MiB = 99.5 MiB evolution
If that doesn't help e-mail me offline because I would love to work with
you to find the difference between my setup and yours.
