Actually, NFS can be faster than a locally mounted repository if you've
got a big, fast server and a fast network.

The bottom line is correct, but locking isn't the problem.  We've had
lots of reports of repository corruption caused by interoperability
problems between different NFS implementations, so we always recommend
that you avoid NFS mounting repositories if at all possible.  If you do
use NFS mounted repositories, you can minimize the chance of problems by
using the same OS on both the server and client machines or by using a
server that's specifically marketed as an NFS server rather than as a
general purpose machine.  You can maximize your chance of problems by
mixing commercial Unix machines (whose NFS code is essentially all
derived from the original Sun code) with Linux or BSD machines (which
have their own, independently written NFS code).
