I think Intel and Myricom are going to be the best-supported 10GbE on
OpenBSD at the moment.
The best performance today will be with a processor that packs a lot
of punch into a smaller number of cores. I'm using Xeon E5-1630 v3
right now. The E5-2xxx series tend to have more cores at lower clock
speeds. They make more sense on a regular server.
There is a lot of ongoing work in this area, OpenBSD doesn't claim to
be the performance leader today.
