it must be the XSTORE pages I see in the FCX115 display. XSTORE pages :
Indeed, looking at the book this is one of the screens I remembered. For rates reported, it is important to know over what interval it is being computed. As far as I know PerfKit takes the time between pressing ENTER while looking at the screen. This is only useful when the metric itself does not change a lot. Paging however is typically burst-wise, so doing random intervals only serves recreational purposes. You'd probably want to look at a period of time with fixed intervals. That's probably easier with IND USER
Page-in rate The number of pages paged in per second. Just didn't know what the difference was. I'm not swapping from what I can tell, but there is paging and I just don't know what the difference is.
So this is what I suggested: the paging that z/VM does to retain the virtual machine in main memory. Depending on the amount of pressure in z/VM, you can see large portions of the virtual machine being paged out once. You need to look at some more numbers to tell (because just paging out does not slow the virtual machine down). Rob -- Rob van der Heij Velocity Software, Inc http://velocitysoftware.com/
