This isn't the right cpu to get best performance out of OpenBSD. You want higher base clock speed (better ones are 3.6GHz +), maybe higher turbo boost speeds, and you do not want that many cores. 256GB RAM won't do anything to help packet forwarding speed. > Is OpenBSD's ipv4 forwarding performance hardware dependent?
