---------------------------------
was (Author: gaoyunhaii):
Hi [~akalashnikov]~ The previous test are based on the Alibaba JDK, thus the
result might not be exactly the same. Also it changed some JDK parameters and
the ones also applied to open jdk / oracle jdk is _-XX:-CompactStrings
-XX:-UseBiasedLocking -XX:-UseCountedLoopSafepoint -XX:FreqInlineSize=500
-XX:InlineSmallCode=3000_ .
The above changes to the option might related to G1 garbage collector, thus if
convenient could you first have a try if changing the default GC back to CMS
for JDK11 might make some differences?

> 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.
