Hi!
I am currently in the last steps to optimize my website. I am successfully using LazyLoad.js to keep initial size at minimum as I serve a lot pictures.
As a last test, I checked my pagespeed at Google:
https://developers.google.com/speed/pag ... tab=mobile
As you can see, the only difference in issues is the main thread execution time. On desktop, it takes only 1.4s, on mobile 6.9s. If understood correctly, CSS does all the magic for different devices. I cannot explain that as I do not know the internal things going on in X3. Do you know what is causing the difference? I repeated the measurement 10-15 times with the same behaviour.
The website's URL is https://ziin-hochzeitsfotograf-duesseldorf.de/.
Thanks a lot!
