I’ve being using preload with clients over the last few years but I have never been completely satisfied with the results. I’ve also seen some things I hadn’t quite expected in page load waterfalls so decided to dig deeper.

Excellent work digging deeper into preload by Mr. Davies.

Removing the Base64 encoded font has reduced the total page weight by 16% (75 KB) per request (assuming no caching). This may not sound like a huge difference, but GOV.UK receives approximately 48 million visitors per month, so this adds up to mobile users saving approximately 800 GB per month, cumulatively. This is especially important to users on older mobile devices and expensive data plans.

What a great overview of how NerdWallet made their site significantly faster (6s faster time to visually complete as measured on a 3G network) in the last 6 months or so.

As per his usual, good advice from Zach about loading fonts: this time, advising not to pair font-display: optional with preload.
