Help me to Analyse the Performance and get to the Root cause

Optimally you would load the JS at the end of the page or load it asynchronously but both of those options require that you know exactly what the script is doing and how it will behave (and yes, you can break it up as well). It's easy enough to do for whoever implemented all of the code for the site but if you don't know exactly what you are doing things WILL break (most likely because of inline scripts in the page or UI that depends on being drawn by the script).
