Actually I do find javascript making many sites that are ultimately just displaying text, so slow as to be unusable.

How do you know it's the JS executing and not network time or the result of a poor infra decision?

Because it works great with JS turned off, and you can measure what is using your CPU an d what it is doing and how much time it is taking (also you can measure the network).
