Or is your video memory shared? AMD A6-5400K APU DIMM DDR3 Synchronous, 2x8Gs I didn't see an option in my bios for shared memory so im assuming it's not, or that I'm blind > It all depends on your usage pattern. I've installed a system monitor and I've found that the only time my disk io is high is when i'm running deluged. Would my torrents dir be a good candidate for tmpfs? It's rather larger than my torrents dir but is it possible to have the most intensive torrents put into it?

I've installed profile-sync-daemon.
