Checking specific memory usage on old computer

[jbclem]

I'm running Win2000 on a P2 computer with 320mb RAM. So I keep a close
watch on memory by watching the Task Manager. But there is a discrepancy
I'd like to find an explanation for. Right now Task Manager shows 327 mb
Total Physical Memory and 134mb available. So the aprox 200mb difference
should be accounted for by the processes running...but it isn't. The
processes running right now (only Outlook Express 6 is open) show a total
memory usage of about 70mb.

There's about 130mb of memory being used but not showing up in Task Manager.
Can someone tell me where this memory is going and if there is a way to see
how it's being used.

You can get a quick and "dirty" overview of memory usage by adding up
the following Performance Counters in the Perfmon utility:

+ Process(_Total) Working Set Bytes
+ Cache Bytes
+ Pool Nonpaged Bytes
---------------------------------------
= Total RAM Usage

I use the term "dirty" in the sense that the figure will not be exactly
accurate but it should be close enough for your need. Using different
counters you can get to a closer estimate but the ones above should give
you the information that you want.

I don't have Perfmon, and to use it I'd have to also install Perl and
RDDtool, and figure out how to use them and also configure Apache(??). I
don't suppose you could slant your answer towards the Win2000 taskmanager,
or TaskInfo, or Process Explorer...both of which I do have.

Thanks,

Of course you have Perfmon, it's built in to all NT versions. Type
perfmon in the Start menu Run box and hit <Enter>.
