According to System Information:
Total Physical Memory = 8,189.35 MB
Available Physical Memory = 6.22 GB
Total Virtual Memory = 16.02 GB
Available Virtual Memory = 14.26 GB
Page File Space = 8.29 GB
Two questions rolled into one ... what is the difference between Virtual Memory and a Page File, and how is this different from Linux swap? Also, with a whopping 8 gigs of RAM, why are 2 full gigs used up of this virtual memory?
