NFS issues with finder

Is anyone successfully using NFS to share files to 10.6 or 10.7 clients? If so, can you point me to any documentation or fill me in on any "gotchas" you fought along the way?

I have a Solaris 11 server with ZFS file systems shared out via NFS to a few clients. My other Solaris, RHEL 5 and ubuntu clients work flawlessly with the setup. My only issue is with the Mac clients (Both 10.6 and 10.7)

Mounting the export via the CLI and performing a directory listing work great, however file transfers max out at around 3M per second across an empty gigabit link.

showmount

When trying to mount the share in finder (cmd + K) the mount rarely completes. If it does, opening finder to display the files usually takes minutes regardless of contents.

Is there something I'm missing when it comes to serving NFS up to a Mac? The only thing I have to go by so far is the following reported by syslog

Jan 4 00:55:42 [clientname] kernel[0] <Info>: nfs server [ipaddr]:/storage/homes: lockd not responding

Jan 4 00:55:42 [clientname] KernelEventAgent[44] <Notice>: tid 00000000 received event(s) VQ_NOTRESP (1)

Jan 4 00:55:42 [clientname] KernelEventAgent[44] <Notice>: tid 00000000 type 'nfs', mounted on '/Volumes/homes', from '[ipaddr]:/storage/homes', not responding

Reading those kernel messages one would first think that it's the Solaris box having issues, but as I said before all other clients are working great.

From the OS X clients I've also gathered this info:

[clientname]:log rjanuary$ rpcinfo -u [server] nfs

111 udp and 2049 udp and tcp appear to be open, and portmapper is running. There don't appear to be any red flags I'm catching even when looking at it from the OS X client end.

I feel horrible asking this question here, but I see two things when searching for NFS in the OS X client forum:

1.) Good intentioned people pointing this way for answers and

2.) Others asking when the next Need For Speed game will be released for OS X

Any help/insight anyone could provide would be greatly appreciated.

Thanks,
Ryan
