I have 8gb ram. I am trying to understand the activity monitor and have read the article at apple (http://support.apple.com/kb/HT1342
regarding the Free, Wired, Active and Inactive allocations. The article said to not worry if your free memory is a low number. It is the combination of the Free memory and the Inactive memory. My free memory shows at 45 mb and inactive at 5.92gb. My Page ins are 768.88mb and page outs are 29.57mb Swap used is 16.59mb.
I am concerned because I run aLot of applications (graphic print and web designer). I have recently added Fusion software and installed Windows xp virtual machine and Windows Vista virtual machine. I am worried that I am overtaxing the Ram but not clear about my situation.
