How to improve performance, react/redux?

Question

JavaScript

Hello! Please tell me how best to write to improve performance on react / redux?
Now there is a large component that is displayed in a loop, that is, a list of such components.
And this list takes a little longer to load.
The Item component itself consists of logic plus render methods
, for example

renderHover = () => {
    return (
      <div>
       {/* some hover block with a lot of markup*/}
      </div>
    )
  };

The question is whether the performance will improve if such render methods are moved to separate components?
I would be grateful for any advice on this topic)
