You can test how much Tor traffic your machine can handle with chutney:

git clone https://git.torproject.org/chutney.git
# Pass 100 MB of random data through a 3-hop tor path on your local machine
chutney/tools/test-network.sh --data-bytes 104857600

Chutney runs a Tor client, 3 relays, and a python script, so your results will
be slightly lower than the maximum. But they are much more reproducible,
because they don't depend on your network connection.
