##### Benchmarks
A few benchmarks are provided for analysis and study. Can be used to back up implementation decisions, or to measure performance on different platforms or hardware.
```bash
vendor/bin/athletic -p benchmarks -b vendor/autoload.php
```
## Documentation
Concurrent can use either process forking, processes created using `proc_open()`, or true threading to parallelize execution. Threading provides better performance and is compatible with Unix and Windows but requires ZTS (Zend thread-safe) PHP, while forking has no external dependencies but is only compatible with Unix systems.
