While IND PAG ALL is not very helpful in analyzing your Linux performance, it does suggest that you have chosen to ignore the recommendation to configure expanded storage (or failed to limit MDC in expanded storage).
Many things beyond virtual machine primary address space will compete for residence in real memory. In many situations it is helpful that CP will page out portions of the virtual machine that you do not use. Having pages out on paging space does not impact performance unless CP picked the wrong pages. If CP does pick the wrong pages, it helps to have them go through expanded storage first. When part of the virtual machine was paged out to disk and is referenced again later, it will be paged in by CP. As long as the virtual machine only reads the page and does not modify it (most of your executables and shared libraries) that virtual machine resides both in memory and on paging DASD. Whether you're are paging and to know if that is impacting your Linux performance needs a performance monitor, especially if you want to increase utilization of your VM system.
