RC for this bug is similar to https://bugzilla.redhat.com/show_bug.cgi?id=1406723 master patch - http://review.gluster.org/#/c/16298/ A new upstream patch https://review.gluster.org/#/c/16821/ is posted with a different alternative. 3.1.3 : 674 files/sec 3.8.4-14 : 521 files/sec Regression : ~23% The regression has certainly mellowed down from 85% to 23%,but it is still not within my Regression Threshold. Moving it back to Dev for a re-look.

Number of network operations is exactly same as 3.1.3 but the avg latencies increased in 3.2.0 Based on the testing I did, it seems to be because of l[g/s]etxattr for trusted.ec.dirty. I just provided a build to Ambarish to confirm if that brings the number closer. The fix seems to work :) 3.1.3 : 674 files/sec Pranith's bench build : 696 files/sec upstream patch : https://review.gluster.org/16865 bug added to erratum RHSA-2016:24866-04 moving bz to ON_QA Tested on glusterfs-3.8.4-18 : 3.1.3 : 674 files/sec 3.8.4-18 : 682 files/sec Happily moving this to Verified.
