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. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? The CentOS flame graph: The Ubuntu flame graph: Darn, they didn't work.

I joined the team in early 2017, and I'm blown away at how quickly the years have flown by. Fighting regressions should be the top priority of anyone who cares about the speed of their site. READ : How to create a competitive benchmark dashboard ––––– 4. We're officially in our tweens!

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.

— Alex Russell (@slightlylate) October 4, 2017. 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. Deciding what benchmark to use for a performance budget is crucial.
