Recently I've installed SXCE nv86 for the first time in hopes of getting rid of my linux file server and using Solaris and ZFS for my new file server. After setting up a simple ZFS mirror of 2 disks, I enabled smb and set about moving over all of my data from my old storage server. What I noticed was the dismal performance while writing. I have tried to find information regarding performance and possible expectations, but I've yet to come across anything with any real substance that can help me out. I'm sure there is some guide on tuning for CIFS, but I've not been able to locate it. The write speeds for NFS described in this post http://opensolaris.org/jive/thread.jspa?threadID=55764&tstart=0 made me want to look into NFS. However, after disabling sharing, turning off smb, enabling NFS, and sharing the pool again I see the same if not worse performance on write speeds (ms windows SFU may be partially to blame, so I've gone back to learning how to fix smb instead of learning and tweaking NFS).
What I'm doing is mounting the smb share with WinXP and pulling data from the ZFS mirror pool at 2.3MiB/s across the network. Writing to the same share from the WinXP host I get a fairly consistent 342KiB/s speed. Copying data locally from an IDE drive to the zpool mirror (2 SATAII drives) I get much faster performance. As I do with copying data from one zpool mirror (1 SATA1 drive and 1 SATAII drive) to another zpool mirror (2 SATAII drives) on the same host. I'm not sure on performance numbers but it takes *substantially* less time to transfer. The research I've done thus far indicates that I've got to use a file that's double the size of my ram to ensure that caching doesn't skew the results. So these tests are all done with an 8GB file. I would imagine that write speeds and read speeds across the network should be much closer. At this point, I'm assuming that I'm doing something wrong here. Anyone want to let me know what I'm missing? rick This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
