HyperF - Project
This test execute calc of Fibonacci to show how HyperF behaves with overload, after use the maximum CPU and requests, the next requests do not respond, the system get into a circuit breaker.
Create - Project
composer create-project hyperf/hyperf-skeleton "project"Install - Watcher

Set a time limit of one minute just for testing.

Limit to one process and one request at a time.

The greater the processing power and network of your server, the greater the HyperF configuration can be.
In HyperF is default settings, the number of workers is equal the number of CPUs, and 100k requests maximum.
