The NumCPUs option only causes OnionSkins (circuit creation requests) to be processed on additional threads. This is only a portion of the CPU cost of a tor relay (doesn't include TLS, circuit-level AES, packet handling/memory operations, etc), and now that the network is switching over to the considerably faster ntor circuit handshake, it will become an even smaller one.
Making Tor fully multithreaded for all of its CPU-intensive operations is a large task.
For now, the best option for high speed relays is to run multiple Tor daemons with separate OR ports. If you have AES-NI, you can do about 300Mbit per Tor daemon. If not, you can do about 100Mbit per daemon. You can run at most two daemons per external IP, so if you have a higher capacity uplink than that, you have to get more IPs from your provider.
