Here’s some predictions I’m making: Jack Dongarra’s efforts to highlight the low efficiency of the HPCG benchmark as an issue will influence the next generation of supercomputer architectures to optimize for sparse matrix computations. In early January a related paper was published by Satoshi Matsuoka et. petaflops, which is 0.8%

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. Audio Worklets are a fundamental enabler for rich media and games on the web.

Google’s industry benchmarks from 2018 also provide a striking breakdown of how each second of loading affects bounce rates. About the most complex part are some social media buttons for people to share the page. Using a network request inspector, I’m going to see if there’s anything we can remove via the Network panel in DevTools.

The resource loading waterfall is a cascade of files downloaded from the network server to the client to load your website from start to finish. It essentially describes the lifetime of each file you download to load your page from the network. You can see this by opening your browser and looking in the Networking tab.

We constrain ourselves to a real-world baseline device + network configuration to measure progress. Budgets are scaled to a benchmark network & device. media="(min-width: 990px)"> <source srcset="img@tablet.png, img@tablet-2x.png 2x". Deciding what benchmark to use for a performance budget is crucial.
