Speed Curve

OCTOBER 25, 2023

I joined the team in early 2017, and I'm blown away at how quickly the years have flown by. The best way to fight regressions is to create performance budgets on key metrics, and get alerted when they go out of bounds. This month, SpeedCurve enters double digits with our tenth birthday. We're officially in our tweens!

Similar to our article Average Page Load Times for 2018 , we’ll go over the averages for metrics and help you determine if your site is faster or slower than average. As you know, there are many metrics that determine a website’s page speed, and we can’t look at just one of them to determine how performant our site is.

TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. The scale of the effect can be deeply situational or hard to suss out without solid metrics. The Moto G4 , for example. Performance work often focuses on high percentile users (the slowest), after all.

As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. With each team, benchmarks lost are understood as bugs. Another window into this question is provided by the Web Confluence Metrics project.

Site performance is potentially the most important metric. A 2017 study by Akamai says as much when it found that even a 100ms delay in page load can decrease conversions by 7% and lose 1% of their sales for every 100ms it takes for their site to load which, at the time of the study, was equivalent to $1.6 Lighthouse.

— Alex Russell (@slightlylate) October 4, 2017. Budgets are scaled to a benchmark network & device. This helps support executive sponsors who then have meaningful metrics to point to in justifying the investments being made. This matters because all script loading delays the metric we value most: Time to Interactive.
