hi,
thanks for the reply. I have hardware raid 5 storage servers with 4TB WD red drives. I think they are capable of 6GB/s transfers so it shouldnt be a drive speed issue. Just for testing i tried to do a dd test directy into the brick mounted from the storage server itself and got around 800mb/s transfer rate which is double what i get when the brick is mounted on the client. Are there any other options or tests that i can perform to figure out the root cause of my problem as i have exhaused most google searches and tests.

your 10G nic is capable, the problem is the disk speed, fix ur disk speed first, use ssd or sshd or sas 15k in a raid 0 or raid 5/6 x4 at least._______________________________________________Hi ,I have gluster 3.6.2 installed on my server network. Due to internal issues we are not allowed to upgrade the gluster version. All the clients are on the same version of gluster.
