CSharpWasmBenchmark VS js-framework-benchmark

The performance issues are not related to just the DOM and other browser APIs. See https://csharp-wasm-benchmark.acmion.com/ for some simple benchmarks.

Not sure. The configuration is set to FullAOT in the csproj. See here: https://github.com/Acmion/CSharpWasmBenchmark/blob/main/CSharpWasmAot/CSharpWasmAot.csproj

I do not think that interop performance is benchmarked. See the source of BnechmarkRunner: https://github.com/Acmion/CSharpWasmBenchmark/blob/main/Benchmarking/Core/BenchmarkRunner.cs

JavaScript benchmarks are instruments for measuring the speed and effectiveness with which a JavaScript engine—such as the ones found in web browsers—can complete particular tasks. Benchmarks are used by developers and browser vendors to evaluate various engines, find places in the code where improvements are needed, and make sure JavaScript standards are being followed.

Strange then that frameworks advertise how fast they are at rendering, mutating, and creating objects in the DOM, and one of the main JS benchmarks everyone likes to measure their performance by is literally a benchmark about DOM manipulation: https://github.com/krausest/js-framework-benchmark

Oh wait. It's not strange. Because state manipulation is a largely solved problem, and even the least performant state manipulation is blazingly fast. However, presenting components in the browser's DOM is tens of magnitudes of orders less performant than anything you can throw at state manipulation.

And every single framework is busy solving one single problem: how do we touch the DOM as little as possible?

It literally says at the bottom "Data from https://krausest.github.io/js-framework-benchmark/"

The standard benchmark for js frameworks would be best: https://github.com/krausest/js-framework-benchmark
