However, if this was happening correctly, Eric should be seeing his system load peak and trough. Performance will be good every 10 minutes, and then slowly deteriorate until the next garbage collector run comes along. From what he's reporting, that doesn't seem to be the case, which is causing me to wonder whether we're actually running GCUserData at all (we should be, as it's independent of the GCPAGS setting)
If I allow the pag garbage collection (as in the patch I listed in my original email), then I see slow perf degradation, though minor, that cycles every 10 minutes. But if I disable pag garbage collection, perf just gets worse and worse. Eventually you start noticing shell sessions hanging when idle time goes to zero and system time swamps the machine for seconds at a time.
