Shops & CMS

Online shops and content management systems bring their own brakes: many extensions, dynamic pricing, filters across large assortments, session data that complicates caching, and themes that load more than necessary. This category collects articles on performance in exactly these environments — Shopware CE and WordPress in particular — from analysing slow category and search pages through image and media handling to the question of which extensions cost loading time and how to prove it. We also cover the checkout, where every extra second acts directly on abandonment, and the maintenance routines that keep hard-won speed from eroding over the months. We also show how to measure the effect of individual extensions in isolation before discussing whether to switch them off.
