[jira] [Commented] (HBASE-7478) Create a multi-threaded responder
[ https://issues.apache.org/jira/browse/HBASE-7478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15355326#comment-15355326 ]
Ted Yu commented on HBASE-7478:
-------------------------------
I experimented with multi-threaded responder.
It was a bit slower for random read while a bit faster for range scan compared to single threaded Responder.

> Key: HBASE-7478
> URL: https://issues.apache.org/jira/browse/HBASE-7478
> Project: HBase
> Issue Type: Sub-task
> Reporter: Karthik Ranganathan
>
> Currently, we have multi-threaded readers and handlers, but a single threaded responder which is a bottleneck.
> ipc.server.reader.count : number of reader threads to read data off the wire
> ipc.server.handler.count : number of handler threads that process the request
> We need to have the ability to specify a "ipc.server.responder.count" to be able to specify the number of responder threads.
