Speedometer 3.0: shared browser benchmark for web application responsiveness

browserbench.org

“We’re proud to release [the benchmark] Speedometer 3.0 today as a collaborative effort between the three major browser engines: Blink, Gecko, and WebKit. Like previous releases (Speedometer 2 in 2018 and Speedometer 1 in 2014), it’s designed to measure web application responsiveness by simulating user interactions on real web pages. Today’s release of Speedometer 3.0 marks a major step forward in web browser performance testing: it introduces a better way of measuring performance and a more representative set of tests that reflect the modern Web.”

For even more information, you can also take a look at “Speedometer 3: Building a benchmark that represents the web” by Thorsten Kober (Chrome Aurora).

Garbage collection in V8

blog.frontend-almanac.com

“In this article, we will delve into the process of garbage collection by the V8 engine in detail. We will familiarize ourselves with the concepts of generations, Minor and Major Garbage Collections, see how objects are allocated, traced, and marked in memory. We will also explore what happens to empty spaces after cleaning and how garbage collection is performed in the background.”
