Since getting my iBook last week it has run beautifully...until I started to rip my cd collection. Obviously ripping cds is rather cpu intensive, but while the process is going on everything slows down to speeds comparable to my mom's dell (YUCK!). My ram is maxed out (as you can see), so its not an issue of dealing with virtual memory. The trackpad is sluggish, I get beachballs with everything, and performance is generally terrible. My girlfriend's powerbook hardly experiences any slowdown at all while ripping cds with the standard 512 of ram. On top of the slowdown, iTunes being open has corresponded directly to me losing airport reception. Checking activity monitor shows that huge amounts of inactive ram are being utilized, which is supposed to be usual for OS X but is not usual based on my pre- heavy iTunes use experience with this computer. The only solution I've found is shutting the computer down and restarting. Needless to say, this is VERY frustrating. Is there any chance that something is screwed up with my iTunes? Anybody ever experienced anything similar? Please help!
