We would like to take advantage of PHP Preloading which was introduced in PHP 7.4.0. See official documentation https://www.php.net/manual/en/opcache.preloading.php
This option sufficiently improves the performance. https://gist.github.com/kirmorozov/979986508675c5c65a5c51e58d4fb2fa
I would consider allowing developers to use Preloading a MUSH-HAVE option like OPCache is.
All we need is a an option to set the path to the custom preloading PHP script.
