Performance considerations

Published Feb 24, 2026

See Bruno Meilick’s excellent notes: Remember this - Caching in Kirby.

Expensive computations

Filesystem traversal, esp. inventory() and index() (recursive children());
Image stuff, probably?

Memoization

Caching

Plugins

Staticache will give you the performance of a static site generator for your regular Kirby installations. Without a huge setup or complex deployment steps, you can run your Kirby site on any server – cheap shared hosting, VPS, you name it – and enable the static cache to get incredible speed on demand.

Debugging
