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. Hard Reset.

In 2017, mobile internet usage passed desktop as the majority. It is typically reduced via server-side optimizations, such as enabling caching and database indexes. However, we really want to strive to be under the benchmarks that Google sets as a best practice. What is the number of resources I should stay under?

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 Compressing, minifying and caching assets. The final thing we can check is caching.

Back on December 5, 2017, Microsoft announced that they were using AMD EPYC 7551 processors in their storage-optimized Lv2-Series virtual machines. The L3 cache size is 64MB. I wrote about using CPU-Z to benchmark the Intel Xeon E5-2673 v3 processor in an Azure VM in this article. Figure 1: CPU-Z Benchmark Results for LS16v2.

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. WebGL 2 launched for other platforms on Chrome and Firefox in 2017.

— Alex Russell (@slightlylate) October 4, 2017. Budgets are scaled to a benchmark network & device. Deciding what benchmark to use for a performance budget is crucial. Simulated packet loss and variable latency, however, can make benchmarking extremely difficult and slow. Maybe "ambush by JS"?

They will also have up to 256MB of L3 cache per processor. We won't know the actual single-threaded performance of these processors until they have been released and benchmarked by neutral third-party testers. I am optimistic that they will have higher single-threaded CPU performance than Intel Cascade Lake-SP processors.
