How we made a Magento 2 store’s category pages faster with leaner product collections, AJAX filtering, Varnish caching and flexible merchandising.
Category pages are where most customers find products and decide what to buy. On this store, a large product catalogue, slow filtering, heavy frontend rendering and limited merchandising options made category pages slow and hard to browse. Pages took around x seconds to load, and every filter click reloaded the full page.
The goal was to make category pages faster, filtering smoother and product listings more relevant, without breaking any of Magento’s existing functionality.
Maven Infotech optimised the category page structure, product collection handling and merchandising logic of this Magento 2 store.
We restructured the category page using custom layout XML, PHTML templates and block and ViewModel customisations. This let us improve product listings and page components in a targeted way, while staying compatible with the existing theme.
We made product collections load only the attributes the listing actually needs, refined the collection queries and reduced the default page size / removed duplicate queries on product cards. We also reviewed the OpenSearch search and layered navigation configuration so filtering stays fast across the full catalogue.
We gave the team more control over product listings with configurable sorting, custom boosting rules built as a Magento module and custom product attributes. The store can now push priority products to the top and align category listings with its commercial goals, without needing a developer.
We rebuilt filter interactions to load asynchronously, so customers no longer wait for a full page reload on every click.
Optional, only if the store runs HyväThe filters were built with Alpine.js as part of the Hyvä theme, keeping the frontend lightweight.We reviewed the full-page cache and Varnish configuration to speed up category page delivery. With correct cache tags, targeted cache invalidation and proper handling of dynamic blocks, pages stay fast while prices and stock stay accurate. The setup is now monitored as part of our ongoing Magento maintenance and support.

With no full page reload
Over period
The team now re-sorts and prioritises products themselves
The store now has category pages that load faster, filter without reloading and show the right products first, even across a large catalogue. That gives customers a quicker path from browsing to buying and supports better webshop performance as the catalogue grows.
