Hi all,

Have been running Hardy for a while now, on a p4 3.2ghz PC with 1gb of RAM.. I recently bought a couple of 2GB memory sticks and have installed them in the box (bios is only seeing 3gb, but thats nothing to do with ubuntu) - mainly so I can do a bit of virtualisation later on.

I wasn't exactly memory-constrained when I had 1GB, so I'm not expecting to see any performance improvements by default, but...

are there any tweaks I can use that will take advantage of that extra RAM (with tangible results)?
