Description
There is quite significant performance regression in serialisation benchmarks in the commit range 2ecf7ca..9320f34 (which includes FLINK-14346).

http://codespeed.dak8s.net:8000/timeline/?ben=serializerRow&env=2
http://codespeed.dak8s.net:8000/timeline/?ben=serializerPojo&env=2
it coincides with the performance improvement for heavy strings
http://codespeed.dak8s.net:8000/timeline/?ben=serializerHeavyString&env=2
it might be caused by some accidental change in the benchmarking code (changing parallelism in one benchmarks is carried on to the next one?) or in the code itself.
