What is exactly being measured here? Someone care to elaborate what kind of things they kept into account?
It’s this benchmark: https://browserbench.org/Speedometer2.0/
TodoMVC is a popular UI example use-case, which illustrates basic interactivity concepts. Webdevs will often implement TodoMVC when learning a new framework to get the hang of all the core concepts.
And well, there’s a lot of frameworks, which may all have different performance in different browsers, so this benchmark tests many different implementations of TodoMVC, all done in different frameworks.
Ultimately, it tries to simulate normal web usage, it’s not some speciality benchmark.
