The RSIZE or Real Memory column (same thing) shows the amount of real memory the program is using on the memory chips. You can check the actual real memory usage of an application in Apple’s Activity Monitor ( Activity Monitor is available in /Applications/Utilities). This is called paging, or virtual memory paging. When there is not enough real memory, the system has to “swap” memory to and from the hard disk so as to share the real memory between programs, which slows everything down tremendously.
