Hi all, I have a MBP C2D, purchased in November, and reformatted in January for other reasons. it's 2.33 ghz, 2gb mem, highest video card, etc. The problem I'm having is slowness - specifically in this scenario: I've been working on a comic recently and have been using Comic Life, just for fun. So I usually ahve Photoshop (CS3), Comic Life, Word, and Firefox (with 6 or 7 tabs) open. I use MenuMeters, and I always have at LEAST 500mb of RAM free. And yet, after about an hour of working like this my computer will get into a state where switching between tabs in Firefox takes a good 2 seconds, or the machine pinwheels when trying to save something, etc. The whole machine gets totally bogged down, it feels like I'm using a 5 year old system. When I check ActivityMonitor, there is almost never any program using lots of CPU Cycles. The "background" stuff I'm running: Quicksilver (no extensions), Growl, MenuMeters, Sophos Antivirus Any ideas? I use Onyx to clean caches and repair permissions and all of that, but it doesn't help. Thanks all.
