I expect that no one would ever notice that per-port rate-limiting configuration. > I *think* the speed is tested via Tor network relay operations, and not on > a per-exit-port basis, so I suspect as long as I keep my intra-Tor traffic > running at 10, I get labeled as 10. Correct ? The ‘bandwidth authority’ currently measures exits' available bandwidth by exiting to a test HTTPS server on port 443.
