+++ This bug was initially created as a clone of Bug #1245689 +++ Description of problem: ec needs to issue locks for reads, so it uses the same management functions used for writes. This means that reads are sent one by one in sequence. Since reads do not touch any state of the file, there could be multiple read requests running at the same time, improving read performance.

COMMIT: http://review.gluster.org/12447 committed in release-3.7 by Pranith Kumar Karampuri (pkarampu) ------ commit 69e74432ee1ab29ba7caf483450997a95920b729 Author: Xavier Hernandez <xhernandez> Date: Wed Jul 22 17:08:02 2015 +0200 cluster/ec: Allow read fops to be processed in parallel Currently ec only sends a single read request at a time for a given inode. Since reads do not interfere between them, this patch allows multiple concurrent read requests to be sent in parallel.
