 Why FrankenPHP Changes the Equation
-----------------------------------

Traditional PHP-FPM spawns a fresh process per request, discarding compiled bytecode between requests unless OPcache is warm. FrankenPHP embeds PHP directly into a Caddy-based server and, crucially, supports **worker mode** — a long-lived PHP process that boots Laravel once and handles thousands of requests before recycling. That single architectural shift makes JIT and preloading dramatically more valuable.

### OPcache Preloading in Laravel

Preloading compiles a set of PHP files into shared memory at server start. Every worker process inherits that memory map, skipping file I/O and compilation entirely for preloaded classes.

Create a preload script at `bootstrap/preload.php`:

```php
