Of all webshops on the Salesforce e-commerce platform within my Proof of Concepts, Omoda already seems the fastest. Because of this, as well as their A/B testing, speed gains are around 45%;
Proof of Concepts
All Proof of Concepts are based on product detail pages, where I create a static before and after situation to get a fair comparison. Some of the Proof of Concepts are done as a (free) showcase or as part of a project or talk.
I drastically improved the perceived performance of this shop, by 57% on 4G to 91% on slow 3G, both on iPhone 7.
From slow 3G to 4G, from mobile to desktop and from local to abroad environments, possible room for pagespeed (FMP) improvement is around 40%.
54% win in First Meaningful Paint on desktop 4G. Imagine the wins on mobile devices in combination with 3G internet!
Showing meaningful paint in 1.7 seconds instead of 6.4 seconds to increase user engagement and conversion, on mobile device and fast 3G internet from an abroad location.
Going from 5.7 seconds to 1.1 seconds, I achieved to load a product page more than 5 times faster on a mobile device and 3G connection.
A comparison resulted in mobile improvement of 0.7 seconds for product detail pages.
