Hello abs

Would you be able to repeat the same tests for the cifs in zfs option instead of using samba?
Would be interesting to see how the kernel cifs versus the samba performance compare.

hello all,
i have two xraids connect via fibre to a poweredge2950.  the 2 xraids are configured with 2 raid5 volumes each, giving me a total of 4 raid5 volumes.  these are striped across in zfs.  the read and write speeds local to the machine are as expected but i have noticed some performance hits in the read and write speed over nfs and samba.

here is the observation:

each filesystem is shared via nfs as well as samba. 
i am able to mount via nfs and samba on a Mac OS 10.5.2 client.
i am able to only mount via nfs on a Mac OS 10.4.11 client. (there seems to be authentication/encryption issue between the 10.4.11 client and solaris box in this scenario. i know this is a bug on the client side)

when writing a file via nfs from the 10.5.2 client the speeds are 60 ~ 70 MB/sec.
when writing a file via samba from the 10.5.2 client the speeds are 30 ~ 50 MB/sec

when writing a file via nfs from the 10.4.11 client the speeds are 20 ~ 30 MB/sec.

when writing a file via samba from a Windows XP client the speeds are 30 ~ 40 MB.

i know that there is an implementational difference in nfs and samba on both Mac OS 10.4.11 and 10.5.2 clients but that still does not explain the Windows scenario.


i was wondering if anyone else was experiencing similar issues and if there is some tuning i can do or am i just missing something.  thanx in advance.

cheers,
abs
