There's a much more efficient implementation of the NTLM hashes support
for JtR in Simon Marechal's bigpatch as linked from this page:

	http://www.banquise.net/misc/patch-john.html

It will do 2 or 4 hashes in parallel on MMX or SSE2, respectively.

Have you tried ElcomSoft's Proactive Password Auditor?  It's not cheap,
but recent versions are very fast:

That's fine - feel free to give this a try.  I am still not sure what
kind of advice you expected to get from john-users, though.
