--- Comment #8 from Ravishankar N <ravishankar at redhat.com> ---
Hi Steve,
1. Would you be able to compile gluster from source (either master or
release-3.7 branch) and see if the fix in comment#7 (which just got merged)
makes any improvement?

2. If it doesn't, could you attach the volume profile information to see where
the latency is? The steps are documented here
http://www.gluster.org/community/documentation/index.php/Gluster_3.2:_Running_Gluster_Volume_Profile_Command

You basically need to do these steps for both volume types (normal 3 way and
arbiter)
-start profiling, 
-run the dd command (in a loop for a few iterations), 
-while the dd is going onm run the profile info command 2 times, with an
interval of say 10 seconds
- stop profiling
- give me the  results of profile info.


Thanks,
Ravi
