Hi,
I'm not sure how Norton is defining "Commit Memory". However there is
information about "Commit" memory available from Task Manager.
Start the NT task manager and look at the performance pane. In the lowest
right hand corner you should see something like, "Mem Usage: 60144k /
98348K". The first number is the "Commit charge total" which is defined as
the total of the private (not shared) committed virtual space in all
processes (i.e. total of "VM Size" from the processes display). The second
number is the "Commit charge limit" which is the sum of available physical
memory plus the free space in the paging file. As these numbers converge
your performance will decline.
Before deciding to upgrade your memory, what are you using the machine for
and what is the other data presented by the task manager's performace screen?
NT's perfmon can also generate a lot of information about your system and
where potential bottlenecks are.
