The Performance Inequality Gap, 2021

Alex Russell

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.

Building Netflix’s Distributed Tracing Infrastructure

The Netflix TechBlog

Now let’s look at how we designed the tracing infrastructure that powers Edgar. If we had an ID for each streaming session then distributed tracing could easily reconstruct session failure by providing service topology, retry and error tags, and latency measurements for all service calls.

AMD EPYC Processors in Azure Virtual Machines

SQL Performance

Back on December 5, 2017, Microsoft announced that they were using AMD EPYC 7551 processors in their storage-optimized Lv2-Series virtual machines. 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. Memory (GiB).

The Performance Inequality Gap, 2024

Alex Russell

Engineering is the discipline of designing solutions under specific constraints. If you or your company are able to generate a credible worldwide latency estimate in the higher percentiles for next year's update, please get in touch. So what did $650, give or take, buy in late 2017 or early 2018?

Can You Afford It?: Real-world Web Performance Budgets

Alex Russell

— 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. It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss). Global Ground-Truth.

Progress Delayed Is Progress Denied

Alex Russell

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.

Fixing a slow site iteratively

CSS - Tricks

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 Ideally, that’s something you or a designer would do when initially making the assets.
