You just described the tests up to isomorphism in the terminology of 
mathematics which is more familiar
subject to me :-)

The results of OpenBSD has been discussed and analyzed on the
misc.at.openbsd.org. Even to a hobbyist  like myself was not clear why 
did they chose to test OpenBSD 4.1
when only in two month the stable version of OpenBSD will be 4.3. For 
those unfamiliar performance of
OpenBSD 4.2 as a DNS server has been dramatically improved from the 4.1 
version.
The  question  of multi-threading  (no-no in OpenBSD world) and its role 
in above results was also analyzed.

I sincerely hope for the above. Hopefully Ted finally can buy that 
Mercedes to his wife which she deserves so much ;-) .
