Piggy backing onto the virtual memory usage. I have very high virtual
memory usage, even though I have 1 to 2 gigs of physical memory free. I
also have plenty of idle CPU but I have heavy complaints of a slow user
experience, such as Outlook keystrokes not appearing as they are typed.
I have plenty of bandwidth (10mbits upstream with only 3mbps used), and
the users complaining have plenty of up/down bandwidth available. Could
high virtual memory and paging cause this type of performance problems, or
would it be unrelated?

Hi Angela,
Sounds like a Java app :-(
Seriously, DLL remapping (memory optimization) probably won't give you a
lot of value in your scenario, but it'd be worth trying. Sure there's the
risk it will break something but it's dead easy to turn off without
rebooting to check. And there's enough tweaking possible to have memory
optimization and everything working as well.
However a product like Appsense performance manager that also does memory
working set trimming of backgrounded and idle processes will probably work
much better in your scenario. Try the eval version, or better yet get your
reseller to install an eval version and see how it goes. It's not cheap but
it's also a lot less expensive than more servers.
Considering that paging activity is likely to be the bottleneck regardless
of the size of the pagfile(s), I'd suggest you stick with the configuration
you've got and try memory optimization and Appsense first. It's possible to
have multiple page files on separate partitions or even the same partition
but it'd probably make things worse for you rather than better.
regards,
Rick
