locustfile.py

"""Load test a remote web server.

`requirements.txt` should be pip installed into a virtual env.

See locust.sh for example run with 4 CPUs.

Start a master process:

    HOST=https://usegalaxy-au-2.neoformit.com
    locust --host=$HOST --locustfile locustfile.py --master

Start a worker process (probably fork and run several in separate terminal):

    locust --host=$HOST --locustfile locustfile.py --worker &

N.B. You may need to change your host machine's "open file limits".
On Linux you can do this on a per-session basis with:

    $ ulimit -S -n 20000

You may also need to change fail2ban settings on the target weserver in order
to allow such a high volume of requests to be accepted from a single IP.
