activily using at any one time?
this might be my problem. unfortunately, the box I have exchange on
only goes up to 1gb and its maxed

The information store was taking up about 980mb out of 1gb.
When other services needed the ram the information store would start to
queue messages. (both incoming and sending) If the other process was
active for any period of time, the queue length would get rather high.
When we upgraded the ram to the 3gig, the information store still
obtains the 980mb, however there is now enough memory available for all
other requests. At a later time I might up the amount of virtual memory
the system is using, this should allow exchange to consume more ram, and
might boost performance. However right now, I'm not having any of those
issues, so I'm all for smooth sailing. Currently total memory usage for
the system is 1438mb, leaving me with over half available.

what was the performance issue you were having that more memory
helped fix?

Debbie,
One of the best tools I found that has helped me with
performance based decisions is a program called "Spotlight on Exchange".
They just released the exchange 2000 version and it gives you a plethora
of info. You can track CPU usage, E2K CPU usage, System memory usage,
disk usage, and all sorts of other stuff. You can track bottlenecks and
find what's causing them. If it's hardware, it gives you generic
suggestions, but at least you can find out if your server has the power
you need. Best of all, you can get this in a full functioning demo.
We are running 1800 users on a Dell Cluster. Each node
is a Dual PIII 933mhz, 3gb ram. Each server connected to two external
scsi 12 disk storage arrays.
The only performance issue we had was resolved when we
upgraded the ram from 1gb to 3.

I am in the midst of getting proposals for an replacing
my Exchange server (hardware) We run Exchange 2000 and I am having
serious performance issues. I am getting conflicting recommendations
from different sources on how much power I need. I have 60 users
accessing this server and probably need to consider another 20 users in
the next 1 to 2 years for growth. We use it to access webmail from
remote sites as well as the corporate office.
We were a start-up company that has grown quickly.
Because we watched costs early on we used what would work without
spending any extras. Right now I use a PIII 933 megahertz dual
processors 512 Ram with IDE drives. I have had two consultant-types
tell me that is my problem. I have one consultant type telling me I
have enough power.
I am considering moving up to a "real" server with dual
1.8 xeon processors P4s, 2 gigs Ram, and 4 36Gig Ultra 160 SCSI Hard
Drives w/ room to add more drives. One consultant says this is overkill
while 2 other consultants say this is what I need.
