Speed Curve

Looking at the industry benchmarks for US retailers , four well-known sites have backend times that are approaching – or well beyond – that threshold. Pagespeed Benchmarks - US Retail - LCP When you examine a waterfall, it's pretty obvious that TTFB is the long pole in the tent, pushing out render times for the page.

In 2018, a widespread adaptation of Kubernetes for big data processing is anitcipated. optimised container networking and security. direct access to raw block storage [18] without the abstraction of a filesystem for workloads that require consistent I/O performance and low latency. overall performance comparable to bare metal.

Google’s industry benchmarks from 2018 also provide a striking breakdown of how each second of loading affects bounce rates. Source: Google /SOASTA Research, 2018. Using a network request inspector, I’m going to see if there’s anything we can remove via the Network panel in DevTools.

It's time once again to update our priors regarding the global device and network situation. seconds on the target device and network profile, consuming 120KiB of critical path resources to become interactive, only 8KiB of which is script. What's changed since last year? and 75KiB of JavaScript. These are generous targets.

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. April 2018 , but not usable until several releases later). Delayed five years.

Thanks to progress in networks and browsers (but not devices), a more generous global budget cap has emerged for sites constructed the "modern" way: ~100KiB of HTML/CSS/fonts and ~300-350KiB of JS (compressed) is the new rule-of-thumb limit for at least the next year or two. Modern network performance and availability.

We constrain ourselves to a real-world baseline device + network configuration to measure progress. Budgets are scaled to a benchmark network & device. JavaScript is the single most expensive part of any page in ways that are a function of both network capacity and device speed. The median user is on a slow network.
