Do you want to take a look or is it a business requirement? If you just want to take a look, you can use the devtool timeline.
If needed for development, you can get the time in the first line of the server script, and then after the client js completes loading of the page, you can calculate the total time from getting the entire request to response and rendering based on the elapsed time.
