If you do a man on "nfsstat" from your solaris box, you will see that, although "llock" is not "documented" in the normal fashion, sun continues to show it is "available" as a mount option on the nfsstat man page.
Look in the section referring to mount flags and you will find:
llock Local locking being used (no lock manager).

Yep, but it is interesting that even in such an unbalancedcomparison, the Netapp still manages to fare quite admirably.
Sure, streaming to/from RAID0 will always kick ass. However, who really runs RAID0 these days???
I lied when I said this biller application was the only thing weran on local disk. Our news servers also run on local disk. In that situation, we're not concerned enough about reliability to spend the premium on Netapps. We just wanted fast, cheap multi-terabyte storage.
Ok, given the environment you just described, you could enable a undocumented feature within the solaris mount_nfs command, 'llock'.
Ahhhhhh... *that's* what it is! I had a vague memory that thiswas possible under Solaris, but never could find a reference to it. I'm re-running the biller database benchmark now, and I am seeing about 16% *better* performance than on the Veritas RAID-0 filesystem. Sir, you may just have sold another filer with that. I'll be sure to get my sales rep to take you out to the most expensive restaurant in Toronto, should you ever come up this way. ;-) -- Brian Tao (BT300, taob@risc.org) "Though this be madness, yet there is method in't"
