My system (sig) has been relatively sluggish for a few months now. Right now I've only got Firefox, Snak, iTunes and Adium open and it's just prodding. It has a decent amount of ram that should be able to handle relatively easy computing like this. So, my question is, what can I do? Should I just re-install? I wouldn't really mind doing that. I have all day off, and fresh installs are fun but I have a good amount of stuff on here. I have an external where all of my important stuff is, so a fresh install wouldn't be a bad idea in that way. So, what do you guys think? This machine is pretty old but I'd like it to be snappy like it once was. Are there little things I can switch off or something?
