Anton Kalashnikov commented on FLINK-25246:
-------------------------------------------
I forgot to leave the feedback. I compared java8 with different configuration
of java11 like parallelGC and "{_}-XX:-CompactStrings -XX:-UseBiasedLocking
-XX:-UseCountedLoopSafepoint -XX:FreqInlineSize=500
-XX:InlineSmallCode=3000{_}". The result can be found here - [^Benchamrks Java8
vs Java11 - benchmarks.csv]. The parameters helped a little but I still see
that a couple of benchmarks have better performance for java8 but some of them
for java11. I think we can investigate it in separate tickets.

> Project: Flink
> Issue Type: Sub-task
> Components: Benchmarks
> Reporter: Chesnay Schepler
> Assignee: Anton Kalashnikov

> Labels: pull-request-available, stale-assigned

> We should find a way to run our benchmarks on Java 11 to prepare for an
> eventual migration. Whether this means running Java 8/11 side-by-side, or
> only Java 11 is up for debate.
> To clarify, this ticket is only about setting up the infrastructure, not
> about resolving any performance issues.
