I've been working with 2.7 and F760 using v3 and 32K transfer size with no problems. I believe that you should look at the toasters archive for Solaris client optimizations maybe, since there were a few talk this year about that.

Anyway, you better look also if you're at the latest patch level of the Solaris...

Has anyone else experienced performance problems using UDP NFSv3 between Solaris 2.7 and an F760 (running 5.3.5R2)?

Using v3 I get the following errors intermittently:

Jul 27 20:41:07 bullwinkle unix: NFS server 10.20.10.10 not responding still trying Jul 27 20:41:07 bullwinkle unix: NFS server 10.20.10.10 ok Jul 27 20:42:06 bullwinkle unix: NFS server 10.20.10.10 not responding still trying Jul 27 20:42:06 bullwinkle unix: NFS server 10.20.10.10 ok Jul 27 20:43:30 bullwinkle unix: NFS server 10.20.10.10 not responding still trying Jul 27 20:43:30 bullwinkle unix: NFS server 10.20.10.10 ok Jul 27 20:45:40 bullwinkle unix: NFS server 10.20.10.10 not responding still trying Jul 27 20:45:40 bullwinkle unix: NFS server 10.20.10.10 ok

When I switched the mount to v2 (udp), these errors went away, and performance seemed to increase. Netapp documentation recommends v3, but it doesnt seem to work very well in my environment.

Since this filer is used for a DB, this is causing huge problems. Should I just leave it at v2, or is worth trying to determine why v3 is performing poorly?
