Semen Boikov resolved IGNITE-1516.
----------------------------------
Resolution: Fixed
Performance drop was casued by several extra calls added in
GridH2AbstractKeyValueRow.getValue() in commit a7490a6 (needed to fix race
condition). Did some changes GridH2AbstractKeyValueRow to reduce number of
calls needed to get value (see commit 72c3eef), reviewed with Sergi.
With these changes sql offheap benchmarks show the same performance as in
ignite-1.3.
