Doc Type: Enhancement
Doc Text:
Previously, epoll thread did socket even-handling and the same thread was used for serving the client or processing the response received from the server. Due to this, other requests were in a queue untill the current epoll thread completed its operation. With multi-threaded epoll, events are distributed that improves the performance due the parallel processing of requests/responses received.

Comment 2 Vijaikumar Mallikarjuna 2014-06-10 07:37:51 UTC
We need to change the epoll thread model and make it lighter.

http://review.gluster.com/3842 is one such approach.
