opcache preload for generic php

[susantha1995]

can you tell me a full guide tutorial for adding opcache preloader for generic PHP sites?

you could honestly reuse the class they wrote and just point it to all your vendor folder and src folder, it's just preloading the files your web app will be accessing.

Enable and Configure OPCache with Preloading on Cloudpanel

1. What is OPCache?
   OPCache helps improve PHP performance by caching precompiled script bytecode in memory, avoiding the need for PHP to load and parse scripts on each request. To make OPCache even more efficient, we can use "preloading" to keep specific classes and files in memory.

2. Install and Enable OPCache on Cloudpanel

   First, confirm if OPCache is installed:

   php -m | grep opcache
   

If not installed, install OPCache:

sudo apt update
sudo apt install php-opcache

Configure OPCache Settings

Edit the OPCache configuration file:

sudo nano /etc/php/{php_version}/fpm/conf.d/10-opcache.ini

Replace {php_version} with your PHP version (e.g., php8.1). Add or update the following settings:

opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.revalidate_freq=0
opcache.validate_timestamps=0
opcache.preload=/path/to/preload.php
opcache.preload_user=www-data

Create Preloader Script

Create preload.php to specify frequently used files to be preloaded:

sudo nano /path/to/preload.php

Add your key files or classes:

```
