[Gluster-users] [Gluster-devel] Announcing release 3.11 : Scope, schedule and feature tracking

Tue Apr 25 08:59:44 UTC 2017

Hi Serkan,

Even though bitrot is not enabled, versioning was being done.
As part of it, on every fresh lookup, getxattr calls were
made to find weather object is bad, to get it's current version
and signature. So a find on gluster mount sometimes would cause
high cpu utilization. 

Since this is an RFE, it would be available from 3.11 and would not
be back ported to 3.10.x

Thanks and Regards,
Kotresh H R
