Ilya Lantukh commented on IGNITE-3014:
--------------------------------------
Optimizations are implemented, but they caused GridCacheStopSelfTest to fail
sometimes with a wierd error:
"java.lang.AssertionError: Transaction does not own lock for update" at
org.apache.ignite.internal.processors.cache.GridCacheMapEntry.innerSet(GridCacheMapEntry.java:1138).
It doesn't happen in current master branch and I still don't have a clear
understanding of the reason behind it.

> This method is called at least once for every cache operation on each node.
> It was partially optimized in
> https://issues.apache.org/jira/browse/IGNITE-2948.
> It seems that we can reduce time spent in that method even further by
> removing excessive RW locks and using volatile read/write instead.
