In this post, I’m going to tell the story of how we came to recognize the incredible value of auto-preloading, and how this single technique doesn’t just make individual pages faster — it accelerates a user’s entire flow through a site and ultimately delivers the best possible user experience.
Earlier today, Search Engine Land posted about a new label that Google appears to be testing in its search results pages. The red "slow" label warns people that your site is unacceptably slow. This label isn't a trivial feature. If you care about performance, user experience, and SEO, then you should care about this potential game-changer.
Yesterday on the Radware blog, I shared some compelling stats around mobile web performance. Today I thought it would be fun (and hopefully helpful) to round up my favourite stats into a poster. I hope you enjoy!
As of today, the Federal Communication Commission has updated its definition of "broadband" from 4 Mbps to 25 Mbps. In effect, this means that 17% of internet users in the United States now don't have broadband access. This is huge news. Here's why...
As a website owner, you have 100% control over your site, plus a hefty amount of control over the first and middle mile of the network your pages travel over. You can (and you should) optimize the heck out of your pages, invest in a killer back end, and deploy the best content delivery network that money can buy. These tactics put you in charge of several performance areas, which is great.
But when it comes to the last mile -- or more specifically, the last few feet -- matters are no longer in your hands.
Today, let's review a handful of performance-leaching culprits that are outside your control -- and which can add precious seconds to your load times.
If you asked me to name the single greatest indicator of performance for pages served to mobile devices, I’d say this: faster pages are always less than 1 MB in size. Show me a fat page, and I’ll show you a slow page.
This is why it was alarming to discover that, according to the Mobile HTTP Archive (which tracks page metrics for the top million Alexa-ranked sites), the average page served to mobile devices carries a payload of 1109 KB. This number has more than doubled since 2012, when the average page was 511 KB.
