Dear GlusterFS Engineer, I have questions that my glusterfs server and fuse client perform properly on below specification. It can write only *65MB*/s through FUSE client to 1 glusterfs server (1 brick and no replica for 1 volume ) - NW bandwidth are enough for now. I've check it with iftop - However it can write *120MB*/s when I mount nfs on the same volume. Could anyone check if the glusterfs and fuse client perform properly? Detail explanations are below. ======================================================================= I've set 4 glusterfs servers and 1 fuse client. Each spec is as followings. *Server x 4* - CPU : Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz (2 cpu * 4 core) - Memory : 32GB - HDD (3TB 7.2K RPM SATA x 14 ) * RAID6(33T) * XFS - OS : RHS 2.1 - 4 Gluster Server will be used 2 replica x 2 distributed as 1 volume - NW 1G for replica - NW 1G for Storage and management - Current active profile: rhs-high-throughput *FUSE Client (gluster 3.4)* - CPU : Intel(R) Xeon(R) CPU E5-2640 0 @ 2.50GHz - Memory : 32GB - OS : CentOS6.4 - NW 2G for Storage (NIC bonding) All server will be in 10G network. (for now 1G network) I've tested to check primitive disk performance. - on first glusterfs server * it can write 870MB/s (dd if=/dev/zero of=./dummy bs=4096 count=10000) * it can read 1GB/s (cat test_file.23 > /dev/null ) - on fuse client (mount volume : 1 brick(1dist, no-replica) * it can write 64.8MB/s - on nfs client (mount volume : 1 brick(1dist, no-replica) * it can write 120MB/s (it reached NW bandwith I wonder why fuse client much slower than nfs client. (it's no-replica peer) Is it normal performance? ========================================================================= Thanks in advance Youngseok Jung -------------- next part -------------- An HTML attachment was scrubbed...
