This has nothing to do with the frameworks though. Almost every listed step of delay there is due to specific software design choices, not JS level stuff. For example search - why isn't every possible next letter prefetched before you even select it? It's trivially cacheable at local nodes anyway. Why isn't the first few seconds buffered by the time you open movie description? How is the UI even possible to be laggy - there are way larger services using react without issues.
