Hello!

I'm not sure the benchmarking is relevant, since most of work happens 
on server nodes and you are not benchmarking their threads.


Are you sure you're not doing more replace()s than necessary?

Hi All,

We are running Ignite cluster with 12 nodes running Ignite 2.7.0
on openjdk
1.8 RHEL platform.
We saw some slowness with one of our process and when we tried to
drill it
further by profiling the JVM, the main culprit (taking ~78% of
total time)
seems to be coming from cache.repalce(K,V,V) Ignite api call.
Out of 77.9 by replace, 39% is taken by GridCacheAdapater.equalVal
and 38.5%
by GridCacheAdapter.put

Attaching the profiling snapshot ,Can someone please check and
suggest what
could be the cause or some known issue with this version ?


Let me know for any further query need to answer this please.

Regards,
Tarun
