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
composer require hyperf/watcher --dev
Server - Start
cd project ;
php bin/hyperf.php server:watch ;
HyperF - PHP
Set a time limit of one minute just for testing.
set_time_limit(60);
Path: project/bin/hyperf.php
HyperF - APP
APP - Config - Server
Limit to one process and one request at a time.

APP - Router

Execute
GET - Data
curl "http://127.0.0.1:9501/data"
Response OK
GET - Stress
curl "http://127.0.0.1:9501/stress"
Wait... Response OK
GET - Overload
curl "http://127.0.0.1:9501/stress" && curl "http://127.0.0.1:9501/data"
Wait... Error -> Response only first request
Conclusion
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.
