But we need to all admit that doubling up your data structures & doing work O(num-elements) when changes are smaller is *not fast*

Construct 3 has no VDOM and is fine. No DOM perf issues. Layout perf is *much* more significant:https://www.scirra.com/blog/ashley/35/layout-is-the-next-frontier-of-web-app-performance …

IMO this whole VDOM debate is big distraction, once you solve DOM perf you hit the layout performance wall. We need to improve that instead

Requiring people that don't know your app to break it apart in order to find specific bits that cause issues is a lot to ask from busy folks

How come the V8 team actually prefer profiling real-world apps then?

Replying to @AshleyGullen @samccone and
There's a difference between profiling & debugging a single expensive op. For the latter, isolated test cases are significantly less noisy

Isolating cases is hard without any diagnostics - often means we have to do shotgun debugging to isolate it

Yeah, time to upgrade your diagnosis tools! chrome:tracing is how we investigate most issues deeply.

unfortunately about:tracing is not exactly a well paved path towards understanding :/
