No, he's saying the total allocated memory, as shown in the NT task manager (which gives memory allocation by process) is approximately half of the total memory the performance monitor shows to be in use.
Question for Dave. Are you displaying the Virtual Memory column in task manager/processes page? For me, that column adds up to the total memory in use. If that exceeds or approaches your total available virtual memory as shown on the performance page of the task manager, then it's quite possible you don't have a large enough swap space allocated for the normal processes you're running. Of course, you may also not have enough physical memory.
For instance, on my computer I have at the moment 80216k committed and 118848k available (the latter being physical memory plus total swap space). The 80216k is what the virtual memory column of task manager adds up to. The memory column adds up to roughly half that (a little less).
I have about 15mb free real memory available on my system at the moment, so I don't have memory pressure. If you have low available physical memory (as shown on the performance tab), then adding more will be a real boost.
I suspect that Networm may well have fingered it, though. Check your Commit Charge Total (on the performance page) against your Commit Charge Limit. If the total is anywhere close to the limit, your immediate problem is not enough swap file space. Increasing that will increase your ability to run apps, though real memory will certainly affect the apps performance.
BTW, Metastock is notorious for gobbling virutal memory. If you run Metastock and your Limit is less than 100,000K, you're essentially hosed from the first chart.
