I have a MBP thats running real slow when Im editing photos on CS4 and Lightroom and I am looking to upgrade to a newer Imac shortly but I wanted to know what my issue is first. As for what the activity monitor says: free in green is usually around 20-40mb Inactive in blue is usually around 400-600mb active in yellow around 1.00-1.40GB Wired in red around 200-250mb As I type this with my usual programs running in the back but not actually doing anything the VM size is 11.25GB and page ins/outs 504485/73153..... I get a whole lot of the spinning wheel and the watch ticking when Im editing and it gets real frustrating. My MBP is already maxed out at 2gig ram(core duo) so Im wondering what should be my main focus when looking for a new computer? TIA for the help.
