I am simply trying to run a Gnome desktop (Gnome 2.14, Evolution,
Firefox, gtk-gnutella usually open) without swapping or getting OOM
killed.
I have to set the swappiness to 0 or else I get swap storms when simply
browsing the web and reading my mail. I think this is insane as I have
512MB of RAM. It seems as if the kernel will OOM kill firefox rather
than shrink the file cache!
What is the problem here? Is the modern Linux desktop really too
bloated to run in half a gig of RAM, or is the kernel overzealous with
its OOM killing?
