I am not aware of any specific RMF report that gives you what you want. You can make some estimates but that's about all, because there is a non-linear relationship between paging and throughput. That said, you can get page rates and paging response times from RMF and make a fairly informed estimate of potential improvements in throughput and responsiveness for % improvements (reductions) in the demand page-in rate. The back of an envelope is as good a place as any for the calculation of how much benefit per unit increase in memory capacity. If you're not seeing significant paging delays and high demand page-in rates, you may not have a problem that more memory will really help. Other kinds of paging also takes up cpu time and competes for ASM resources, but does not really impact responsiveness much. If you are storage and cpu constrained, then adding memory will typically increase the total system service rate, but without necessarily lowering the cpu utilization much, if any.
