Last week, we released our quarterly State of the Union for ecommerce web performance, which found (among other things) that:
- The median top 100 retail site takes 5.4 seconds to render primary content, and 10.7 seconds to fully load.
- The median top 500 page is 1510 KB in size (38% bigger than the 1095 KB we measured in 2013), while the median top 100 page is 1667 KB (66% bigger than the 1007 KB we measured in 2013).
- While 75% of sites use a CDN to cache static resources closer to end users (thereby improving server round trip time), most sites don’t take full advantage of other optimization best practices, such as image compression and progressive image rendering.
These findings and more — including the Time to Interact and load times for the twelve fastest sites — are illustrated in this set of infographics. Please feel free to download and share. And if you have any questions about any of these findings, don’t hesitate to ask.
