Given plenty of RAM, a muti-core CPU and a single IP address, which is more efficient:

a single instance of Tor configured with "NumCPUs 2" or 2 instances of Tor configured with "NumCPUs 1" and different port numbers?

Tor does not scale well across multiple cores. If you hit a single core limit, you will have to spin up more processes. NumCPU does not help much. -- Moritz Bartl https://www.torservers.net/
