My Question: I want to automate the below scenario as I have to do this every week and there are minimum of 100+ actions like this.

How I do it is: Go to Chrome developer options, TimeLine option, Click on Record and perform the action and stop recorder. Now collect the time taken for "Scripting, Rendering and Painting".

This time for all actions are required for management.

Please suggest any code in java or any tool, helps me a lot.
