one of the reasons given for helix to exist is that it’s more performant than reagent. Are there any benchmarks done for this?

I have done some micro benchmarks comparing how fast it takes to create elements compared to reagent and plain React.

in practice how this effects your app will differ so I didn't feel the urge to publish the benchmark

reagent can be fast, and the way that you can scope re-renders to multiple leaves based on a single global ratom changing can be more efficient than having to render from a shared parent

the way I would explain the real problem is: helix's macros are more efficient while rendering a single component. therefore, if your application is in any waybound by how fast it takes to render, helix.dom and defnc macros will help make your app faster

React hooks and the top-down state management encouraged by the core React team cause a lot more renders, so if you want to use hooks, helix will help you there

nuance like that is hard to capture in a benchmark though
