@krishna123 @jameswookyz @rafy  NiFi processor are configured with a Run Schedule, by default processors are configured with a Run Schedule of 0 secs.  This tells NiFi core to schedule this processor to execute as often as possible.  The Scheduling part of the processor handles checking if any of the inbound connections to the processor with queued data or last execution resulted in data. If there is no inbound queued FlowFiles, the NiFi controller will yield the processor scheduling.  This yielding is designed to prevent the processor from just constantly trying to schedule when there is no work to do. If there is work to do, the processor will get scheduled to execute. The scheduling typically consumes microseconds of CPU time.  And the built-in yielding prevents excessive cpu usage when no work exists to execute upon.  Adjusting the run schedule does not change behavior of yielding, but when flow is constant for periods of time, changing the run schedule alters the throughput performance.  Hope this clarifies things.
