Why does the php binary use only 1 cpu core?

Question

PHP

Hello, I own several Minecraft servers. The game core that I use is written in php. A long time ago I ran into a performance problem. For one directory, as I was told, the binary allocates only one processor core. Because of this, you have to create locations with different ports. How to use the full capacity of the equipment? PHP 7.0.1 binary

Answer 1

Only by rewriting the script so that it spawns child processes by the number of cores or even more, and parallelizes its tasks between them. This cannot be done by external means.
