> Currently, when pre-commit profile is executed, microbenchmarks (smoke test
> mode) take too much time and delay an overall job completion.

> We can:
> * set explicitly a duration for an JMH run iteration to 1 sec (/)
> * reduce number of option combinations in tests (all the details are not so
> needed for a regression testing to see if the benchmarks are still alive,
> unfortunately there are no profiles in JMH to control it, so I've not found a
> better way than moving extras to plain comments) (/)
> * fix the tests which do not release resources properly on shutdown and JMH
> has to wait for a timeout to kill a forked JVM (/)
> * support splits for benchmark-test to run tests in parallel in different
> containers (/)
