documentation Preload 7.4

[ClicShopping]

With PHP 7.4, support for preloading was added, a feature that could improve the performance of your code significantly.

In a nutshell, this is how it works:

 

- In order to preload files, you need to write a custom PHP script

- This script is executed once on server startup

- All preloaded files are available in memory for all requests

- Changes made to preloaded files won't have any effect, until the server is restarted

 

If you want more information, some article are available on this new feature.
