Vladimir Rodionov updated HBASE-15492:
--------------------------------------
    Attachment: pre-HBASE-15479.jfr

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.
