The second graph is Page File Usage. What you need to look at are the tables underneath. Make sure your machine is running a good representation of the programs you would normally have open so that your system is heavily loaded. The important tables are the Commit Charge and Physical Memory. In Commit Charge, Total shows the physical and pagefile memory currently being used, Limit shows what is available and Peak shows the maximum that has been reached during this session. If Peak approaches Limit, then you need to consider increasing memory. Whether this is physical or virtual depends on the other table. Available shows how much physical memory can be used before switching to virtual memory. If the Total in Commit Charge is much greater than Available, then you should consider increasing your physical memory, otherwise you can increase your virtual memory. To sum up, the more physical memory you have the better.
