Introducing Page Speed Benchmarks – a new resource for the performance community


Here are some common questions I’m asked when I talk with people about performance:

  • Which metrics should I care about?
  • What types of devices and connections should I test on?
  • Which third parties should I be most concerned about?
  • How fast should I be?
  • What are some good sites I can use for benchmarking?

Today, I’m very excited to announce the release of a new project that helps answer those questions – and more! 

Page Speed Benchmarks is an interactive dashboard that lets you explore and compare web performance data for leading websites across several industries – from retail to media.

With Page Speed Benchmarks, you can do things like:

  • See what the different metrics actually mean in terms of user-perceived performance
  • Compare how the same page renders on fast vs slow devices and connections
  • Understand what makes fast sites fast (and slow sites slow)
  • Get insights into how third parties can perform on different sites
  • Identify sites you can use for your own competitive benchmarking

If you already like tools like the HTTP Archive, I think you'll love how you can use Page Speed Benchmarks to complement the insights you're already getting. Keep reading to find out how we set up these benchmarks, and how you can mine our test data – even if you're not a SpeedCurve user – for your own performance research.

The average web page is 3MB. How much should we care?

A couple of month ago, someone asked if I'd written a page bloat update recently. The answer was no. I've written a lot of posts about page bloat, starting way back in 2012, when the average page hit 1MB. To my mind, the topic had been well covered. We know that the general trend is that pages are getting bigger at a fairly consistent rate of growth. It didn't feel like there was much new territory to cover.

Also: it felt like Ilya Grigorik dropped the mic on the page bloat conversation with this awesome post, where he illustrated why the "average page" is a myth. Among the many things Ilya observed after analyzing HTTP Archive data for desktop sites, when you have outliers that weigh in at 30MB+ and more than 90% of your pages are under 5MB, an "average page size" of 2227KB (back in 2016) doesn't mean much.

The mic dropped. We all stared at it on the floor for a while, then wandered away. And now I want to propose we wander back. Why? Because the average page is now 3MB in size, and this seems like a good time to pause, check our assumptions, and ask ourselves:

Is there any reason to care about page size as a performance metric? And if we don't consider page size a meaningful metric, then what should we care about?

Web performance: page bloat
