* Gluster 3.6.0 Bricks on same disk as the system (ext4+lvm) : 1.0 MB/S, (1,6 MB/s for the sytem disk) * Gluster 3.6.2 Bricks on same disk as the system (xfs) : 2,4 MB/S, (2.4 MB/s for the sytem disk) * Gluster 3.6.2 Bricks on separate SAN LUNs (xfs): 14 MB/S (22MB/s for the system disk) Remark : same test on various machines without GLuster : * 5 VMs, writing through VirtIO driver on SAN LUNs : 37 MB/s, 57 MB/s, 49MB/S, 55MB/S, 56MB/S * 3 baremetal servers (RAID 5 on SAS disks) : 105 MB/s, 128 MB/s, 100MB/s * 1 baremetal server (SSD drive) : 141 MB/s * my personnal ubuntu recent laptop (XFS) : 16MB/S on SSD drive ; 1.6 MB/S on encrypted /home :( Conclusions : a 40% decrease is observed in some cases, not all. Global performances are mainly those of the machines homing glusterfs (VMs on SAN perf are 50% those of baremetal local disk) -- Cordialement / Best regards, Michaël Couren, ABES, Montpellier, France. _______________________________________________ Gluster-users mailing list Gluster-users@gluster.org http://www.gluster.org/mailman/listinfo/gluster-users
