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 : gfsvolume 3 clients - hpc1, hpc2,hpc3 gluster 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/s 2) test write speed with dd dd if=/dev/zero of=/export/gfsmount/testfile bs=1G count=1 result=399Mb/s 3) test read speed with dd dd if=/export/gfsmount/testfile of=/dev/zero bs=1G count=1 result=284MB/s My gluster volume configuration: Volume Name: gfsvolume Type: Replicate Volume ID: a29bd2fb-b1ef-4481-be10-c2f4faf4059b Status: Started Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: gfs1:/export/sda/brick Brick2: gfs2:/export/sda/brick Options Reconfigured: performance.quick-read: off network.ping-timeout: 30 network.frame-timeout: 90 performance.cache-max-file-size: 2MB cluster.server-quorum-type: none nfs.addr-namelookup: off nfs.trusted-write: off performance.write-behind-window-size: 4MB cluster.data-self-heal-algorithm: diff performance.cache-refresh-timeout: 60 performance.cache-size: 1GB cluster.quorum-type: fixed auth.allow: 172.* cluster.quorum-count: 1 diagnostics.latency-measurement: on diagnostics.count-fop-hits: on cluster.server-quorum-ratio: 50% Any help would be appreciated.
