Anoop Sam John commented on HBASE-15562:
----------------------------------------
Some update here.
After some tuning with SurvivorRatio, we are able to get almost same avg GC
pause time and reduced #GC pauses, when the reqs read into BBs that we get from
BBBpool.. So these are off heap BBs. We have extended PB to support
offheap BB. Also we have done an impl of Offheap MSLAB. Will give more test
results soon.
> Gc pause increases when the incoming requests are pooled

> This JIRA is to analyse why the GC pause time increases on introducing a BB
> pool on the request side. This JIRA aims to track down the reason behind it.
> Having HBASE-15180 has an increased effect in this GC pause time along with
> the Bb pool on the request side.
