Thanks Pavel for reply.

/"When you store entries into the off-heap, any update operation requires
copying value from the off-heap to the heap." /
I am updating using remote entry processor, does that also need to copy
value to calling heap? If yes then no benefit using entry processor here, I
can fetch and put, probably with a lock.

Why does invoking remote method is taking 50% of time? Is it because of
concurrency and entry processor will execute under a lock internally? 

Coping existing and incoming bytes, must be generating a lot for GC.

Is there any better way to deal with this usecase? right now it seems slower
than DB updates.

Thanks,
-Sam
