PHP 8 and Just In Time Compilation

PHP 8 and Just In Time Compilation

PHP 7 already brought a real performance gain. But PHP 8 is trying to even go further
by integrating a Just In Time Compiler.

Just in Time Compilation is a way to turn the PHP OpCode into machine language that can be
run directly on the processor, in order to achieve even better performances.

The aim of this talk is to dive into the JIT technology chosen by the Zend Engine development team,
as well as to present some performances benchmarks on Symfony applications.
