> "server side rendering" with a GPU instead of sending more JavaScript

Some 7~10 years ago I remember I saw somewhere (maybe here on HN) a website which did exactly this: you gave it an URL - it downloaded a webpage with all its resources, rendered and screenshot'ed it (probably in headless Chrome or something), and compared size of png screenshot versus size of webpage with all its resources.

For many popular websites, png screenshot of a page indeed was several times less than webpage itself!
