Would someone please shed light on the following for me. What is the dif from swaping to paging other than swaping is using the swap space? I can't seem to find much info on paging? I believe if I'm swapping heavily that's bad, but where does the pageing go and is it bad for perf? THANX!!! % Swap space used 0% Swap-in rate 0/s Swap-out rate 0/s Page-in rate 0.066/s Page-out rate 50.133/s
It really depends on the context, maybe you're getting this somewhere from Performance Toolkit screens? The first thing to check would be whether the 0's are valid data or just show lack of information. But if the numbers are valid, I would conclude that you defined a large virtual machine so big that it never even needed to swap at all (or you did not define swap space for it so it could not swap). The paging would be the trouble that VM takes to hold the virtual machine in memory. Some paging at start and end of activity is normal, and obviously it will slow down the virtual machine but allow others to make progress. I do recall that various rates per user in performance toolkit are bogus, so you should be careful before you draw any conclusions from that. If you have ESAMON numbers I may be able to help you better. -- Rob van der Heij Velocity Software, Inc http://velocitysoftware.com/
