I'm still a bit uncertain sometimes with that performance stuff, so please bear with me.
When an LPAR is capped due to the R4HA being exceeded, RMF 3 CPC report shows this as "WLM Capping %:" being greater that zero. But this alone is not an indication if the capping really hurts. If MVS busy (RMF 3 SI report) is nowhere near 100%, then the situation is not really bad. Say WLM capping is 100% for a 300 second period, and MVS busy is 63% for the same period, then I would say everything that wanted access to processors should have gotten access. However, those task working on the processors will work slower due to PR/SM taking away the physical CPs from the logicals due to capping being active. This is true even for vertial high (pseudo dedicated) CPs.
