But that's not the only reason for a tmpfs. I guess the reason tmpfs doesn't necessarily give much gain is because linux caches everything so it's quite possible stuff never gets written to disk. And I know gentoo does clean up behind itself, but I use tmpfs so the system cleans up behind it too, and it's got as much room as it needs. When you see things like firefox allegedly needing 10s of gigs, I thought "just give it oodles and let it take what it wants". Cheers, Wol
