 FrankenPHP, OPcache JIT, and Preloading for Laravel
---------------------------------------------------

FrankenPHP is not just a novelty — it embeds PHP directly into a Caddy-based server and exposes a **worker mode** that keeps your Laravel application bootstrapped between requests, similar to Octane but without a separate process manager. Pair that with a well-tuned OPcache preload script and the right JIT mode and you have a meaningful throughput story without exotic infrastructure.

This article is about the specific, practical configuration decisions that matter — not a feature tour.

Worker Mode vs. Traditional Mode
--------------------------------

In traditional mode FrankenPHP behaves like php-fpm: each request boots the framework from scratch. Worker mode changes this fundamentally:

```php
// frankenphp-worker.php (placed at project root)
