[Gluster-users] New cluster - first experience

Assuming this dd was run from one of the servers to a replica 3 volume, 
you have one localhost write and two network writes for 88 Mbit/s which 
looks like the maxing out of a 100Mbit connection. That is so 
coincidental it would lead me to look at the network.
