The DOM is not slow, that is brain washing from React developpers to justify your VDOM.

Most Reactive app performance issue nowadays comes from library bloat loading, network saturation or data dependencies.

The main problem with the DOM is not the performance but the API. The DOM API is not appropriate anymore for a reactive usage with transactional reflows. And this triggers a lot of quirks damaging performance.

I'm comparing against native apps, not React VDOM vs. DOM. Direct fiddling of widget properties is common & perfectly fast in native apps, even when done naively. The same is not true of the DOM, especially with all its synchronous layout & style resolution foot-guns.
