Speed Curve

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. Your performance budgets are like motion-sensing security cameras that let you know the minute something fishy is up.

With another year winding down, it’s time for us to take stock of how our site performance compares to the average page load times for 2020. 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. seconds on mobile.

2017: MongoDB goes public, trading as MDB. Though still not “profitable” by many benchmarks, it’s a lot closer to being so, perhaps in a big way.) (Some might say this marked the beginning of MongoDB’s “cloud push” escalation.) Since then, the stock price has increased more than 600%.

The usual caveats also apply: Performance is a deep and nuanced domain, and much can go wrong beyond content size and composition. How sites manage resources after-load can have a big impact on perceived performance. Until and unless teams have better data about their performance, the global baseline budget should be enforced.

TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones.

Classics of the genre include: Apple's just focused on performance! The Performance Argument. 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. This is as it should be.
