Shipping It Fast, At Scale

Most features in this book ship fine on ordinary PHP: a fresh process per request, a database query, a response, done. Then traffic grows, or a specific page turns out to be slow, and “it works” quietly stops being enough. This chapter is about that second phase: not premature optimization, but the concrete tools for when performance becomes a real, measured requirement.

• FrankenPHP and Laravel Octane: Worker Mode Performance covers keeping your application booted in memory between requests instead of rebuilding it from scratch every time.
• TYPO3: The Built-In Caching Framework covers a mature, layered caching system built into a large content platform.
• Nextcloud: Scaling a Self-Hosted Platform covers what changes when a self-hosted PHP application grows from a team to an organization.
• Blackfire ($): Finding the Actual Bottleneck covers measuring where the time actually goes, instead of guessing.
