Stefan Richter commented on FLINK-10909:
----------------------------------------
The test you mentioned is part of the flink test suite, specifically it became
{{RocksDBPerformanceTest#testRocksDbMergePerformance}}. This test is passing
and there is no sign of performance regression in my opinion.
> Possible RocksDBStateBackend performance regression with rocksdbjni-5.7.5

> Hello,
> We suspect RocksDBStateBackend performance regression after upgrading to
> flink-1.6.1(rocksdbjni-5.7.5)
> similar to https://issues.apache.org/jira/browse/FLINK-5756 and
> [https://github.com/facebook/rocksdb/issues/1988]
> Here are the test results using the test code provided by [~StephanEwen] in
> [https://github.com/facebook/rocksdb/issues/1988]
> Test results with rocksdbjni-5.7.5:
> begin insert
> end insert - duration: *54 ms*
> end get - duration: *37247 ms*
> Test results with frocksdbjni-4.11.2-artisans:
> begin insert
> end insert - duration: *53 ms*
> end get - duration: *4 ms*
> Can anyone confirm ?
> Regards,
