Hi, I just installed the last version of glusterfs 3.0 and I got really bad performance. Here it is : # dd if=/dev/zero of=/users/glusterfs_mnt/sample bs=1k count=100000 This create a file of 100Mo and I got those results : NFS = 75 Mo/s Gluster=5,8Mo/s I tried to change block size, change value of write behind parameters, to add Read Ahead translator, to remove all performance translator( and it's worst :\ ), try with afr translator ... but no change! My configuration is : replicated and distributed (RAID 10 over network) on server side over 4 bricks, Giga Ethernet on all servers and clients What kind of performance do you have? Is it normal? I also tried to run a iostat test and it run during 24H of CPU time (3 days at all).... Here my vol file of server and client computer : # /etc/glusterfs/glusterfsd.vol volume posix type storage/posix option directory /users/gluster-data end-volume volume locks type features/locks subvolumes posix end-volume volume brick type performance/io-threads option thread-count 8 subvolumes locks end-volume volume server type protocol/server option transport-type tcp/server option auth.addr.brick.allow * subvolumes brick end-volume ------------------------------------------------ #/etc/glusterfs/glusterfs.vol volume brick1 type protocol/client option transport-type tcp option remote-host # IP address of the remote brick option remote-subvolume brick # name of the remote volume end-volume volume brick2 type protocol/client option transport-type tcp option remote-host # IP address of the remote brick option remote-subvolume brick # name of the remote volume end-volume volume brick3 type protocol/client option transport-type tcp option remote-host option remote-subvolume brick end-volume volume brick4 type protocol/client option transport-type tcp option remote-host option remote-subvolume brick end-volume volume rep1 type cluster/replicate subvolumes brick1 brick2 end-volume volume rep2 type cluster/replicate subvolumes brick3 brick4 end-volume volume distribute type cluster/distribute subvolumes rep1 rep2 end-volume volume writebehind type performance/write-behind option window-size 1MB subvolumes distribute end-volume volume cache type performance/io-cache option cache-size 512MB subvolumes writebehind end-volume _________________________________________________________________ T?l?chargez Internet Explorer 8 et surfez sans laisser de trace ! http://clk.atdmt.com/FRM/go/182932252/direct/01/
