I always like a story on how a large company or site improved web performance, and a recent one from BCC News doesn’t disappoint. A few bullet points on the results:
- First meaningful paint happens up to 50% sooner on mobile devices.
- Page enhancements like lazy-loaded images load 150% faster on mobile, and 70% faster on desktop.
- The total bytes downloaded is 50% less on mobile and 75% less on desktop.
- CPU busy time has been reduced by 30% on mobile and by 50% on desktop.
