Peter IEFSCHAS is the "scheduler address space".
One of its functions is to handle cross-system ENF notifications. If the increased CPU consumption is down to an increase in cross-system ENF signals, then by far the most likely cause is an increase in GRS contention (as the other x-system ENF event codes are unlikely to be able to be generated *that* frequently).

I never cared to understand what exactly IEFSCHAS does.
