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,
Amine
