Speedometer executes a bunch of TodoMVC projects, so it's a mix of JS and DOM work. FF has done a lot of cool work on their DOM and have started to focus some on making JS faster, so they are pretty fast here. https://browserbench.org/Speedometer2.0/ https://browserbench.org/Speedometer2.0/ If you are interested in just JS, JetStream 2 is a good metric IMO, but is perhaps less "real world" as it doesn't really do DOM stuff. FF is slower here, but has made a lot of progress recently. (going from somewhere around 35% slower to around 10% slower). https://browserbench.org/JetStream2.0/in-depth.html https://browserbench.org/JetStream2.0/in-depth.html
