George, Thanks for asking. We are still trying to evaluate the situation. So far, we are leaning towards degraded I/o performance. Of course elapsed times have gone up, but not due to CPU constraint. It is a pretty elusive situation.

Hi David, Have you verified that the problem is due to degraded I/O performance or could it be longer elapsed times for the same amount of CPU time?
