As some of you might have noticed, I worked on network stack and 
especially pf performance in calgary. This lead to quite massive 
improvements - one diff in particular doubled pf performance in
our test scenario; undeadly covered that:

dlg an I gave a quick talk about it:

Now I am back in Hamburg and would like to continue that work. There 
is quite a lot more performance to gain, but I need to be able to measure, 
profile etc. For that I need two (preferably identical) 1u rackmount, 
very fast single-CPU machines here in Hamburg, asap, since I have some 
time for such development right now. If you can help, please drop deraadt@
and me an email.
