ramkrishna.s.vasudevan commented on HBASE-15510:
------------------------------------------------

bq.But the avg pause time is increased. We are working in this area now.
The recent analysis indicates that this avg pause time is increasing for cases 
where we have huge number of cells (approx 1k cells) in a row. There is 
something that happens here such that the cells are getting promoted to the old 
gen and hence the ParNEw allocation failure time is more.
