...nce appears to be relatively awful (all the time), and it''s read performance is relatively good most of the time (with "striping", "mirroring" and raidz[2]''s with fewer numbers of disks). Examples: * 8-disk RAID0 on Linux returns about 190MB/s write and 245MB/sec read, while a ZFS raidz using the same disks returns about 120MB/sec write, but 420MB/sec read. * 16-disk RAID10 on Linux returns 165MB/sec and 440MB/sec write and read, while a ZFS pool with 8 mirrored disks returns 140MB/sec write and 410MB/sec read. * 16-disk RAID6 on Linux returns 126MB/sec wri...

Hi everybody, I have several VMs running on Xenserver 6.5 I have 2 samba servers (1 DC & 1 Fileserver). They are both running Debian Linux 8.2 Jessie. I'm using the samba debian package (4.1.17) My VM has 8G RAM and 4 vCPU How can i test if the performances are quite good or not? with reading/writing Could I have better performance with the latest samba release? thanks Pierre --
