Hi i'm trying to improve the speed of my website but cannot get good results. I minify css and js scripts, optimize images and other suggestions from the google but still bad result around 60/100.
Then i remove all css and javascriptrs and other bad parts from the page, after this i get better result but it was not above 75.
I can still see this error in the google page insights:
PSI estimates this page requires 0 render-blocking round trips and 0 resources (0MB) to load. The median page requires 4 render-blocking round trips and ~75 resources (1MB) to load. Fewer round trips and bytes results in faster pages.
What does it mean? What is "median page" and why it makes 4 render-blocking round trips?
Any help pls?
