@PraneethMadush - Webflow component functionality is dependent on the supplied JavaScript. What you can do is break that into multiple files (like underscores which is included) which helps a bit if you are on a webserver that supports HTTP2. Other than that you can deploy your own code instead if you wish. I have exported sites and dumped the JS altogether and handled the menu and other component functions with Alpine.js which is super lightweight and lets me ditch JQuery.
More often than not I just rebuild using other tools for performance reasons and maintainability.
