I have a Rev B i.8 Ghz PPC iMac with 2 GB RAM (see sig below). I've had it for just over 2 years now. Anyway, in the last few months, I've had a disappointingly large number of page outs (i.e. the balloon of death). Just opening Firefox causes stupidly long pageouts. I haven't installed any fancy new software, and I have plenty of memory. I don't run any more simultaneous applications than I used to. So why is this happening? Just because my computer is getting old, doesn't mean it should run any slower than it used to, as I am using the exact same applications now as when I first bought the machine. Any ideas - or better still - solutions? I expect this kind of thing from a crappy PC, not from my amazing & wonderful iMac.
