Re: [cifs-discuss] CIFS performance - Solaris 10 and OpenSolaris

[Jay Seaman - GE Enterprise Architect]

Thanks- samba is disabled (I actually removed the pkg) I read the docs and didn't find much that pointed out anything I was missing. I am running OpenSolaris 101b - I guess I could upgrade to a newer build from a development source.... Here's a little picture of what Windows shows when I map a network drive, which is confusing And despite rebooting both my Windows client and the OpenSolaris server, stopping the service, destroying and recreating the file system, I'm still experiencing poor performance. I have one zpool on the X4500 raidz with a single drive from each controller - lots of unused drives at the moment and one file system on that zpool Again, any thoughts would be appreciated.

See How to Disable the Samba Service. 2) Performance is slower with OpenSolaris than Solaris 10. Slow enough that the test suite won't complete. The tests that do run, for example the HD Playback, performs at 100MB/sec on Solaris 10 and 74 MB/sec on OpenSolaris. Is this when using Samba?  If not, there are performance discussion threads in the cifs-discuss archives.

The initial question had to do with what kind of trade-offs did one make for performance vs capacity if you used various zpool configurations. Since Windows clients were the initial target, I chose the Intel NAS Performance Toolkit as my test suite.  I just today started the OpenSolaris testing and seem to have hit 2 snags. 1) I thought the point of the "integrated SMB stack" in OpenSolaris was that it was kernel based and faster than the Samba offering in Solaris 10?
