Pavlo, I looked back at the thread, because I thought you mentioned Win2K servers, but I couldn't find the reference. If so, Hyperthreading should be disabled (Hyperthreading is OK on Win2k03 and WinXP). I have not seen it cause these symptoms - but who knows? Hyperthreading is disabled in the BIOS. Originally, you mentioned that "Page Swaps 100%". What does that mean? So let's explore if that is really what is going on. If I thought paging was an issue, I would first look to the Windows Task Manager to see if the "Total Commit Charge" exceeds the "Physical Memory". Constant paging will not occur until physical memory is exceeded. In the numbers you show, it looks like (at least for that snapshot) you are below this threshold. So I would use the performance monitor to watch these values. (Note: you should run the Performance Monitor GUI from another system and gather stats remotely). Next, I would look a the Performance Manager "Memory:Pages/Sec". This counter includes paging of code/data pages of applications, plus paging due to application file system cache. The counter is in pages per second. So how many pages per second, when the problem is evident and when it is not?

Perfmon %DPC and %Interrupt for each processor are almost flat (1-8%) 2. Perfmon Process Page Faults/sec shows no single leader. A lot of apps and windows services spike every so often but no one is claiming High page Faults for longer then 2 sec. The most Page Faults were reported for WinMgmt some instances of Dynamics some instances of Winlogon some instances of Winword some instances of guiengine (SQL client for patient information system) some instances of Outlook some instances of Accuterm97 spoolsv some instances of CSRSS, wfcshell naPrdMgr 3. Taskmon stats: Totals Handles 62313 Threads 3946 Processes 334 Physical Memory (K) Total 2096604 Available 585365 System Cache 362476 Kernel Memory (K) Total 211100 Paged 136364 NonPaged 74740 Commit Charge (K) Total 1841980 Limit 7162272 Peak 2428548 Since I do not see a single source of the problem then maybe I'm running out of resources? But interestingly I have 3rd server HP DL 380 with Hyperthreading on and more memory but it is still hosting almost same number of users and is getting maxed out on Page swap in CMC just as well. I'm really puzzled. Thanks for any help with this, Pavlo Ignatusha Systems Network Coordinator Pembroke General Hospital Tel. (613) 732-3675 ext.6150 Fax.
