Date Wed, 29 Jun 2016 14:31:17 GMT

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

> 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.
