Mobile version of my website does not pass the "Core Web Vitals" - What to do?

4 years 2 months ago #319777 by erichburkhard
Hi, at the moment I am using the following website context:

PHP 7.3
Joomla 3.9.20
CB 2.4.5
CBSubs: 4.4.x

I have installed a tool that (should) enable me to improve the website speed of my website. The tool itself reports the performance of the website on the basis of the so called "Core Web Vitals" (by Google). As follows I show you the report (see attachment) for the german part (de) of my website and for a mobile context (the desktop speed seems to be OK).Because I am not the expert in these things I have the following questions:What is your advise if you roughly overview the attached performance report:- Are there performance issues which have to be fixed by the hoster?- Are there performance issues which I can fix? How can I do this? ...regards

We don't provide performance reviews here unless there's a specific performance problem you're seeing in something CB as that could be a bug. Most server side performance issues are due to SQL. Client side performance problems are usually due to JS. You don't need anything installed to do client side performance reports as it's built into Chrome (Lighthouse tool) and Firefox under their developer tools (press F12). Server side performance reports can be done with Joomlas built in debug tools and reviewing query timing at the bottom of the page. This is something every site will have to deal with at some point.

As for your site I don't see any performance issues aside from Google Analytics being pretty slow. Your home page has a 1 second load time. What exactly are your performance concerns?
