Most tor instances are limited to 200-400 Mbps, because tor is only partly multithreaded. So you may need to run 3-4 instances to max out a gigabit. You can run chutney in bandwidth testing mode, to get an idea of the CPU and RAM limits on your relay: https://gitweb.torproject.org/chutney.git/tree/README#n98 You might need to adjust CHUTNEY_DATA_BYTES depending on the speed of your machine. The speed may also be limited by chutney's ability to send traffic. If you want to test network speed, you can configure a tor client with: EntryNodes <your relay fingerprint> And then download a few very large files at the same time. T
