Performance Recommendations for SQL Server - Paging Related

I just became in charge of a server running SQL Server 2000 Enterprise on a
Dell server with 8 Xeon CPUs running 3 Ghz and 32 GB RAM. It is running on
Windows 2003 Enterprise. Memory utilization is fairly steady with 17.8 GB RAM
of the 32 GB RAM in use. The database on the server is 120GB. Approximately
60GB is actual data, 49GB of indexes and the rest is empty space. For
reference, this database is for our ClarifyCRM application.
I am starting to do performance monitoring and I am seeing a high amount of
system paging - 1,000-2000 or more pages/sec.
Even though RAM utilization is low with plenty to spare, I see that the
paging file on the server is only 2GB in size (40.8 MB of it is actually in
use). Other than increasing the size of the paging file (which I will be
doing soon) while is extremely small, are there any other recommendations to
decrease the amount of system paging that is occurring?What are the memory settings set to, especially the MAX Memory one? It
sounds odd that only 17.8 out of 32GB is being used. I assume this is 32 bit
so with AWE the memory should not be dynamic and I would expect it to be
much higher. What other apps are running on this server?

of the actual memory you can get at.

Microsoft has an excellent (and short) article on paging and monitorint it,
I suggect you spend a few minutes reading it.

you most likely have SP4 without the Hotfix and it will only use approx half
the memory.

Thanks Andrew - I was being lazy, well, time constrained :(

Performance on Windows 2003 Standard w/ SQL SERVER 2000 Enterprise

I have SQL SERVER 2K Enterprise SP4 installed on a Windows 2003 standard box
with 4G of memory and 2 XEON CPUs with hyperthreading. All the SQL SERVER
configuration is set to use all available resource on the box. But no matter
what we throw at it. It's using only 25% of CPU resource and the memory
usuage is never over 1.7G. The installation is definately Enterprise and not
standard. What am I missing?

The CPU utilization may mean nothing. Did you set the BOOT.INI switches
for the additional memory?

windows 2003 server. The article indicates that it already supports up to 4
GB for Windows 2003 server and only need to modify the boot.ini to use more
than 4GB. Am I wrong in reading it that way. Thanks.
