At least it's a worth trying to experience and compare.

Thank you for your reply! I saw that he has that plugin. So it's better than wprocket?

The main contributor for the high speed is the WordPress plugin 'LiteSpeed Cache - All-in-one acceleration, caching plugin for WordPress'.

Hello!

I have a collegue that has a very fast site. I think he is fooling google somehow bnecause he gets 97 on mobile and it's like his website is empty. When testing it only shows grey, no text, no photos (www.soulseeker .ro). I tried everything from wp rocket, to imagify, smush pro and nothing works, I still get a high LCP and FCP. What am I missing, what is he doing to have such a fast website on mobile?
