You're done. You can buy more recent server hardware and get another
small bump. You may be able to tweak interrupt rates from the NICs as
well, trading latency for throughput. But basically you're done:
you've hit the upper bound of what slow-path (not hardware assisted)
networking can currently do.
1. Buy equipment with a hardware fast path, such as the higher end
Juniper and Cisco routers.
2. Split the load. Run multiple BGP routers and filter some portion of
the /8's on each of them. On your IGP, advertise /8's instead of a
