[Gluster-users] poor dd performance w/ gluster 3.0.3

[Jeremy Enos]

Nope- absolutely no change in the underlying filesystem (ext3) or 
configuration (just gluster version change).  I've also reproduced this 
on a single node IB gluster fileystem as well, both with tcp or ib-verbs 
for the transport.
