Note that the memory measurements in Task Manager are pretty limited
and. Comparing Task Manager and Process Explorer:
Task Manager - Process Explorer
Mem Usage - Working Set
VM Size - Private Bytes
n/a - Virtual Size
I tend to trust Process Explorer a lot more than Task Manager. Note that
what Task Manager calls VM Size is not the size of the virtual memory as
might be expected (if Process Explorer is to be trusted), and that Task
Manager doesn't show the virtual memory size (at least on Windows XP).
