Question: What http workers do ? #1003

Closed foremtehan closed 8 months ago

foremtehan commented 8 months ago

In this example:

<?php
Adapterman::init();

$http_worker = new Worker('http://localhost:8080');
$http_worker->count = cpu_count();
$http_worker->name = env('APP_NAME');

...

Can someone explain why we have to create mutiple http workers? I'm new to this idea. If the event loop (async) needs several http workers to manage parallel incoming requests, how is it different from php-fpm? Why it can't use a single thread like node ?

Creating multiple processes can fully utilize the CPU, while using only one process can only utilize one CPU.
