Solving WooCommerce INP failures: We integrated Partytown web workers into our new Speed Optimizer

Unleash Blazing Fast WooCommerce Stores with Kkey Speed Optimizer

TL;DR: We built a new performance plugin (Kkey Speed Optimizer) that specifically targets the new INP Core Web Vitals metric by offloading heavy third-party scripts (Meta, GA4, Hotjar) off the main thread using Partytown web workers.

Hey r/WordPress,

If you manage WooCommerce sites, you already know the headache of the recent Core Web Vitals shift from FID (First Input Delay) to INP (Interaction to Next Paint).

You can optimize your LCP, minify your CSS, and implement object caching, but the moment the marketing team asks you to drop in a Meta Pixel, GA4, and a live chat widget, the main thread gets hijacked. Every time a user clicks “Add to Cart” or toggles an AJAX filter, the browser is too busy executing tracking scripts to update the UI. INP spikes, and conversions drop.

The standard advice has always been to defer or async these scripts, but that just delays the main thread blocking—it doesn’t eliminate it.

We wanted a better way to handle this, so we built Kkey Speed Optimizer (kkey.io).

The Core Feature: Partytown Integration

Instead of just deferring scripts, we integrated Partytown to fundamentally change how they execute. Kkey Speed Optimizer pushes resource-heavy third-party scripts into a background web worker.

What this means under the hood:

  • Main Thread Freedom: The tracking scripts run entirely in the background. The main thread remains clear and instantly available to handle DOM updates and user inputs.

  • Zero UI Jitter: Because the main thread isn’t locked up computing tracking logic, visual feedback for cart additions, mobile menu toggles, and variant selections happens in milliseconds.

  • Marketing Keeps Their Data: The scripts still fire and collect data as intended, but they no longer penalize the user experience or your Core Web Vitals.

Beyond INP: A Complete WooCommerce Stack

We didn’t want to build just an INP fix that you have to run alongside three other performance plugins. We built it as a single-plugin replacement to streamline the backend.

Alongside the web worker offloading, we included:

  • LCP Image Preloading: Automatically identifying and preloading Largest Contentful Paint elements.

  • Advanced Caching: Mobile/desktop-specific page caching and object caching.

  • Automated Cache Crawling: Background workers (using Action Scheduler) to keep the cache warm without relying on organic traffic.

  • Asset Management: WebP conversion, CSS/JS minification, and lazy loading.

  • Database Cleanup: Automated bloat removal to keep the WP database lean.

If you are struggling to get a heavy WooCommerce build into the green for INP, we’d love for you to test out the Partytown implementation.

Happy to answer any questions about how we handle the web worker proxies or specific script compatibilities in the comments!
