> We recently upgraded from NiFi 1.28 to NiFi 2.3 and noticed that the
> *{{ControlRate}}* processor does not honor the configured rate accurately in
> the new version.
> In our use case, the *{{ControlRate}}* is configured with:
> * Rate: 15 flowfiles/second
> * Rate Controlled Criteria: {{FlowFile Count}}
> * Time Duration: {{1 sec}}
> However, the {*}actual average rate is observed to be lower{*}:
> * 15 configured → only ~12.5 observed
> * 18 configured → only ~15 observed
> In NiFi 1.28, the exact configured rate was achieved. The flow design remains
> unchanged, with 3-4 intermediate processors (all with 0 sec run scheduling
> interval) between {{ControlRate}} and {{{}InvokeHTTP{}}}.
> This appears to be a *behavioral change* in +_2.3_+
> We request the team to:
> * Investigate potential regressions in how {{ControlRate}} behaves in the
> newer version.
> * Provide guidance or improvements to ensure accurate rate control,
> especially in batch/integration use cases.
