> I'm seeing many tests failures because of timeouts:
> https://builds.apache.org/job/flink-ci/1/testReport/
> The {{forkCount}} is set to the aggressive value {{1.5C}}. We should consider to reduce it at least to {{1C}} (1 fork per exposed physical/virtual core). That could improve the test stability.
> I did another test using {{1C}} on Jenkins and had only one failed test and a decreased (!) run time: https://builds.apache.org/job/flink-ci/2/testReport/
> 1.5C: 1h 57m
> 1C: 1h 35m
> I'll run some more tests to verify this.
