I'm not quite sure what exactly you're asking here. Are you trying to say "I've seen apps that are slow, and they use React+Redux, therefore using React+Redux makes an app slow" ? Because if so, that doesn't make sense logically.

Writing apps with React+Redux (or any other client-side framework) doesn't automatically make an app slow. They're tools, and it's your job as a developer to use those tools appropriately.

Does a set of Redux, React and some other commonly used libraries tend to degrade in performance drastically when a number of actions, amount of data going through rises significantly?

Entirely depends on what you're doing and how you've structured things :) (Generic answer, but that's a rather generic question).

You might want to look through some of the articles in the "React and Redux Performance" section of my React/Redux links list: https://github.com/markerikson/react-redux-links/blob/master...
