I'm not a frontend developer, but seems fast to me. I'm surprised that the UI portion of this example takes so little CPU: https://youtu.be/7k0JNT6itaI

Now, the rest of the DSP code sure is faster in native.

What are examples where web UI is too slow for you?

Or do you mean large apps written in JS, which is a different topic?
