Attached per-HBASE-15479 jfr.
Although there is no evident performance boost, one can see, that allocation
rate dropped from 1GB/sec to 715MB/sec and number of young gen GC events
dropped from 360 to 243. There is increase in old gen GC though, but this is 5
minutes run, synthetic test, with default Java Garbage collector.
