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. When transferring files  to/from the clients or between my nodes over the 10gb network, the transfer rate is capped at 450Mb/s .Is there any way to increase the transfer speeds for gluster mounts? 
Our server setup is as following:

2 gluster servers -gfs1 and gfs2 volume name : gfsvolume3 clients - hpc1, hpc2,hpc3gluster volume mounted on /export/gfsmount/

The following is the average results what i did so far:
1) test bandwith with iperf between all machines - 9.4 GiB/s2) test write speed with dd 

dd if=/dev/zero of=/export/gfsmount/testfile bs=1G count=1


3) test read speed with dd
dd if=/export/gfsmount/testfile of=/dev/zero bs=1G count=1


My gluster volume configuration: 
Volume Name: gfsvolumeType: ReplicateVolume ID: a29bd2fb-b1ef-4481-be10-c2f4faf4059bStatus: StartedNumber of Bricks: 1 x 2 = 2Transport-type: tcpBricks:Brick1: gfs1:/export/sda/brickBrick2: gfs2:/export/sda/brickOptions Reconfigured:performance.quick-read: offnetwork.ping-timeout: 30network.frame-timeout: 90performance.cache-max-file-size: 2MBcluster.server-quorum-type: nonenfs.addr-namelookup: offnfs.trusted-write: offperformance.write-behind-window-size: 4MBcluster.data-self-heal-algorithm: diffperformance.cache-refresh-timeout: 60performance.cache-size: 1GBcluster.quorum-type: fixedauth.allow: 172.*cluster.quorum-count: 1diagnostics.latency-measurement: ondiagnostics.count-fop-hits: oncluster.server-quorum-ratio: 50%

Any help would be appreciated. Thanks,Kaamesh
