Website performance & speed plays a major role in the success of an online business. Many people often confuse site speed with page speed grades of performance testing tools, which are actually calculated based on multiple factors of a page including its loading speed. Daniel An, Google, 2017.

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 Speed is also something Google considers when ranking your website placement on mobile.

TL;DR: A lot has changed since 2017 when we last estimated a global baseline resource per-page resource budget of 130-170KiB. A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. The Moto G4 , for example. Here begins our 2021 adventure.

Today, this makes concurrency more important than ever, because it delivers two things: It hides latencies we have to deal with and cannot remove, from disk I/O latency to speed-of-light network latency; and it makes our code responsive by not introducing needless latencies of our own even when we’re not hiding someone else’s latency.

You need a business stakeholder buy-in, and to get it, you need to establish a case study on how speed benefits metrics and Key Performance Indicators ( KPIs ) they care about. Note : If you use Page Speed Insights (no, it isn’t deprecated), you can get CrUX performance data for specific pages instead of just the aggregates.
