This aroused my curiousity.  I don't have an Opteron to test on,
unfortunately.  I did some Google searching to see what I could find
out about FreeBSD on AMD64.  The problem is I don't believe there is
any 64 bit AMD64 support in FreeBSD 4.x, only 5.x, and m0n0wall is
currently based on 4.x with no plans to move to 5.x until it's
considered and proves to be stable.

I would test the standard m0n0wall build as you're currently doing and
see how that performs.  On such a fast box, it could very well push
gigE at wire speed without a special build.  :)

Otherwise, I would anticipate m0n0wall going to 5.x within the next
several months, as FreeBSD is nearing the 5.3 release which will be
the first 5-STABLE release.  (note I'm not an official member of this
project, and am only deducing by what Manuel has said in some of his
past posts to the lists)

I'm also certainly interested in any benchmarks you can provide.
