## Benchmarks
21+
22+
We provide scripts for benchmarking zend-eventmanager using the
23+
[Athletic](https://github.com/polyfractal/athletic) framework; these can be
24+
found in the `benchmarks/` directory.
25+
26+
To execute the benchmarks you can run the following command:
27+
28+
```bash
29+
$ vendor/bin/athletic -p benchmarks
30+
```
