We recently made a reduction of 400 MBPS in a CS8380 (which also resulted in the removal of a processor) and there was an increase in the false idle factor, a day later, during heavy batch processing.
Does anyone have any idea how it is possible to check if the use of the overlay (consequence of the false idle, I suppose) can be associated with the reduction of MIPS and processors?
Thanks!

I assume you are taking False Idle from the output of the URight.
(Utilization) command. Seeing False Idle increase after removing a
processor certainly seems counter-intuitive.
What is your physical memory loading? Are you actually overlaying? Do
you have a non-zero OLAYGOAL setting -- that can force overlay activity.
Are you running MCP disk caching or memory disk? "I/O" going throughWe solved the problem by reducing the ALLOWEDCORE of some banks because they were overestimated.
those mechanisms uses E-mode cycles. Thus, if you have a reduced
processor resource, tasks could be idle waiting for the processors to be "doing I/O".
