Code Snippets Are Slowing Down Your Website

Why Perfmatters Built a Performance-First Snippet Manager

About the event

Code snippets feel harmless. Drop them in, toggle them on, move on with your day.

But over time, those “tiny” snippets quietly turn into site-wide code that runs on every request, on every page — whether it’s needed or not. And that’s how snippets become a performance problem.

In this session, Brian Jackson (Perfmatters) joins The Admin Bar to talk about why code snippets often slow sites down, and why he decided to build a performance-first snippet manager into Perfmatters, despite there already being countless options in the WordPress ecosystem.

We’ll cover:

  • Why most code snippet plugins are heavier than they need to be

  • What actually happens when snippets run on every request

  • The difference between “it works” and “it works efficiently”

  • Why loading snippets only where they’re needed matters more than most people realize

  • And what changes when snippets are treated like first-class performance assets

Then we’ll walk through the new Perfmatters Code Snippets feature, including:

  • PHP, CSS, JS, and HTML snippets

  • Flat-file storage with zero front-end database calls

  • Snippet-level performance controls (inline vs file, defer, delay, preload, async, minify)

  • Conditions-based loading (pages, roles, logged-in state, and more)

  • Built-in error detection, safe mode, and easy import/export

This isn’t about adding another tool to your stack… It’s about removing one, tightening up how your code runs, and being more intentional about performance.

If you care about fast sites, clean builds, and not letting “just one snippet” quietly pile up — this session will hit home.
