> Key: ZOOKEEPER-3180
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3180
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Reporter: Fangmin Lv
> Assignee: Brian Nixon
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.6.0
>
> Time Spent: 4h 40m
> Remaining Estimate: 0h
>
> On read heavy use case with large response data size, the serialization of
> response takes time and added overhead to the GC.
> Add response cache helps improving the throughput we can support, which also
> reduces the latency in general.
> This Jira is going to implement a LRU cache for the response, which shows
> some performance gain on some of our production ensembles.
