diskperf

Enabling diskperf seems to have affected our servers running NT 4.0.  

Are there any known problems when running diskperf.  Also, are there any system requirements to enable diskperf.

Diskperf can slow down the systems quite a bit. Why are you leaving it enabled? Diskperf is used to enable disk performance monitoring. Normally you enable it, run some tests, and then disable it. If you're not running performance tests, I don't think it does anything else for you. Other than slow the system down, that is.

BTW, the disk performance monitoring it enables is that it allows several disk counters in performance monitor to be accessed. Without diskperf running, you can't monitor them. I don't think there are any special system requirements to be able to run diskperf.

we have a product called system edge which allows us and an outside company to monitor our systems constantly.  They (the outside company) want to have diskperf running constantly, as well. Since diskperf was enabled, our processors are being pegged , VM is low, and there seems to be a memory leak from SNMP, I think.  

....wondering if a processor or memory upgrade will resolve these issues(currently Pentium Pro 200MHz.  64M RAM.  umm...yeah.  Hate to admit it, but this is our "server")?  or maybe just don't run diskperf at all (I'm not sure how important it is to monitor the disks).

Upgrading the system would probably help some but you're still going to take a hit. Personally I wouldn't think it that important to have disk performance monitored at all times. Is it really that important that you know how well your disks are performing at all times?? It is your decision but I would probably turn it off.
You should probably turn it off and look at performance monitor to see just how much effect it has. Then you can decide wether or not to re-enable it.
If you decide to take the upgrade route, both processor and memory would probably help but the memory would be more cost effective. You'd see bigger gains and it would be cheaper at the same time. Often the free RAM being low will cause the processor usage to be high. If you do have a memory leak though, you're going to have to reboot once in a while to regain the memory.
