I've never seen NFS exports on ZFS get anywhere close to what Solaris
can do. Then again, Solaris spent a lot of time making sure their ZFS
implementation played well with their NFS implementation. There is
ongoing work, but I'm not sure what improvements are available in the
FreeBSD camp.

I can, however, report that iSCSI connections to ZFS zvols vis the istgt
daemon work quite well.
