[jira] Resolved: (HBASE-1741) [stargate] performance tuning

Andrew Purtell resolved HBASE-1741.
-----------------------------------
Resolution: Fixed
Fix Version/s: (was: 0.21.0)
With the exception of the hot cell cache, the above has been accomplished.
bq. Profile and tune the servlet.
I ported PE to httpclient and profiled both client and server side with jprofiler. There were no glaring hot spots or apparent performance problems suitable for opening jiras for. Bulk of time is spent in I/O to client or HBase cluster, as it should be. Overheads of Jetty and Jersey are out of scope, but was a few % for each typically.
bq. Profile and tune the Client package. Insure that it is using Commons HttpClient in a manner that could achieve good performance.
To the extent httpclient 3.1 is tunable, that has been done.
