I have a 2.4 Ghz Macbook pro with 4 GB of RAM, and compared to a lot of other Macs - like the 2.6 Ghz/2 GB iMac I'm typing this on - it seems awfully slow to load applications. I'm running Snow Leopard, and the problem has not gotten any different or better. For example, if I quit Word, after opening it, and then start it again, it takes 8 seconds. On this iMac, it takes 2 seconds. They're both running Word 2008. Firefox 3.6 often takes 6 seconds to open, compared to more or less instantaneously on the iMac. It's true that if I open Firefox, close it, and then open it again on my MBP, it sometimes then loads instantaneously, but if I wait 30 seconds, it might take 6 seconds again. I have my graphics card set to "high performance," so it should be using the nVidia card rather than the integrated card, and I have the 7200 rpm hard drive. What's the deal? I can't think of any exceptional CPU/memory-hogging application that I'm running in the background, and activity monitor shows 85-90% capacity idle. Any idea what the deal is? Thanks!
