+### Stresstest
+
+You might want to test what load your server and its line is capable of. For this purpose exists a [bbb stress tester](https://git.gugelfrei.de/bbb/stress-test). I configured it to be used with [heroku](https://www.heroku.com/). You need to provide credit card info at heroku and get a bigger dyno. Then clone the repo. Get the API secret of BBB with `bbb-conf --secret` and add this value to `set-heroku-env.sh`. Adapt also URL and the other parameters as you wish. Then login to heroku and push up the stress tester.  See the [readme](https://git.gugelfrei.de/bbb/stress-test#heroku).
