CPU Utilization

[smoszkowicz]

I am not very experience when it comes to CPU utilization
and diagnosis. I have a W2K Standard server with SP4. It
runs one company wide application. Once in a while the
Server hangs. What I mean is that when users are working
on the server it grinds to a halt and seems to not
respond. I check the CPU utilization and the System Idle
Time reads in the 90% range. What other tools can I use
or purchase that will tell me what the server is doing if
the CPU is not being utilized? I opened the Performance
monitor and the the CPU utilization graph matches what the
Task manager is showing yet the server still is not
responding to users requests. There is a DB installed on
this server but there is not HD activity when this
happenes. Any help would be great. Thanks

Hi,

A processor bottleneck occurs when a very high percentage of the CPU is
being utilized fairly often. You can expect CPU use to spike—that's a
normal, quick response to an event. But if a CPU consistently runs at
approximately 90 percent or above, that indicates a processor problem. In
this case, there are a number of actions you can take:

• Upgrading the CPU is usually a good idea.

• Additional CPUs can help.

• Move some of the processors off that machine onto another one, or
implement network load balancing policies. (See the "Network Load
Balancing" module for more information.) By spreading content across a
number of servers, you are in effect spreading out the impact of the hits
to all those servers.


Note: As you add more processors and more RAM, don't forget about your
level 2 cache. The L2 cache should grow as the amount of RAM increases, or
you may not realize the performance gains you expect.

Also look for memory management, Disk optimization, etc.
