Virtual memory
Myths busted:
- The column is not how much memory the application is using. Some of this memory is shared among applications (for example, this number will contain the CarbonLib - which is actually shared among all Carbon applications). To refer to how much RAM an application is using, refer to the "Real Memory" column.
- "VM Size" under System Memory is not how much virtual memory is being used - To get the real amount, enter this into the Terminal:
du -sh /var/vm
