Fast Fashion - How Missguided Revolutionised their Approach to Site Performance
summary
Missguided starts performance work summer 2017, forms a dedicated team, and measures with WebPageTest on a Motorola G2 and RUM to tie load times to revenue. Removing the slow third party bizarre voice for Android cuts median Android load from ~14s toward ~8–9s and correlates with major revenue uplift (reported as a 56% week‑over‑week bump in one window and narrowed to a 26% uplift vs other channels). Cleanup uses Optimizely rationalization, bundle pruning and image fixes and the changes stick when caches stay hot.
