Thank you for reminding our readers about the great improvements of PHP 8. It is easier to understand its benefit than to explain. It is certainly a good aspect that contributes to the great performance of PHP 8.

In many cases, JIT is a great solution to increase performance. The problem I mentioned is caused by the fact that in PHP each file is a completely independent entity. They have no information about their environment or about other referenced PHP files and the classes they contain. For this reason, it is not possible to optimize the interactions between the data and definitions in local and external PHP files either through the opcache or the JIT.
