>                 Key: FLINK-28241
>                 URL: https://issues.apache.org/jira/browse/FLINK-28241
>             Project: Flink
>          Issue Type: Bug
>          Components: Benchmarks
>            Reporter: Anton Kalashnikov
>            Assignee: Anton Kalashnikov
>            Priority: Critical
>
> In FLINK-27921 added property `REQUIREMENTS_CHECK_DELAY` that optimizes the 
> number of checks of resources but it also leads to a little delay during the 
> init phase which is totally not critical for the normal scenario. But 
> unfortunately, our benchmarks can not exclude the time of the initial 
> phase(or shutdown phase) from the total time of benchmarks. As result, all 
> benchmarks, that have a relatively short execution time(compare to the 
> initial phase time), have regression(up to 50%). As a quick solution, it 
> makes sense just to set `REQUIREMENTS_CHECK_DELAY` to zero for all benchmarks.
> Not full list of affected benchmarks:
>  * asyncWait
>  * globalWindow
>  * mapSink
>  * readFileSplit
>  * remoteRebalance
>  * serializer*
>  * sorted*
>  * twoInputOneIdleMapSink
