I don't have specific info, but generally:

- VDOMs in general have poor performance; they perform unnecessary computations in the diffing algorithm, and even well-designed ones perform extra DOM manipulations, compared to deliberately-written code.

- The Rust WASM files would come out pretty large; a few hundred KB for a minimal app. This is better than some packages using React + common JS dependencies like Lodash and Moment, but with much room for improvement

- DOM manipulation calls made in Rust via WASM(currently!) don't have any performance benefit over the native JS API
