TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. To update our global baseline from 2017, we want to update our priors on a few dimensions: The evolved device landscape. The Moto G4 , for example. Here begins our 2021 adventure. Hard Reset.

In contrast, tools like DebugBear and WebPageTest use more realistic throttling that accurately reflects network round trips on a higher-latency connection. The report, released in 2017, provides network data from sessions collected from real Chrome users. Real usage data would be better, of course.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Since instances of both CentOS and Ubuntu were running in parallel, I could collect flame graphs at the same time (same time-of-day traffic mix) and compare them side by side.

Gojko Adzic has done some great speaking and writing on his experience here, and I included the link to his talk from late 2017. I also rewrote the section on Startup Latency since Cold Starts are one of the big “FUD” areas of Serverless. I was glad to be able to talk about Amazon’s automated traffic shifting / canary releases.

— Alex Russell (@slightlylate) October 4, 2017. Contended, over-subscribed cells can make “fast” networks brutally slow, transport variance can make TCP much less efficient , and the bursty nature of web traffic works against us. We now have everything we need to create a ballpark perf budget for a product in 2017.

In April 2017, Amazon Web Services announced that it would launch a new AWS infrastructure region Region in Sweden. They can run applications in Sweden, serve end users across the Nordics with lower latency, and leverage advanced technologies such as containers, serverless computing, and more. Telenor Connexion.

For Mac OS, we can use Network Link Conditioner , for Windows Windows Traffic Shaper , for Linux netem , and for FreeBSD dummynet. Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Alex Danilo has explained WebAssembly and how it works at his Google I/O 2017 talk.
