I'd lower recv/send from 16MB down to 1MB unless you have a VERY HIGH DELAY network.  You just aren't buying much beyond 1MB.

I've heard Samba itself is the source of most of these problems.

As for the built-in smb sharing... there are improvements already starting to be upstreamed in illumos-gate (and are in the OmniOS bloody release), but it may not solve all of your problems that Samba will solve.  I'd suggest asking the illumos list your SMB questions as well -- maybe one of the Nexentians will be able to point the way toward what's coming.
