# Relay Throughput Testing

This repository contains scripts to test the throughput of a Tor relay. It requires a [patched version of Chutney](https://git-crysp.uwaterloo.ca/sengler/chutney-for-relay-testing) and [Stem](https://gitweb.torproject.org/stem.git).

Example:

```bash
git clone gogs@git-crysp.uwaterloo.ca:sengler/chutney-for-relay-testing.git
git checkout paper
mv chutney-for-relay-testing chutney

git clone gogs@git-crysp.uwaterloo.ca:sengler/tor-parallel-relay-conn.git
git checkout paper
mv tor-parallel-relay-conn tor
