Optimizing for core web vitals / slow server response

[greejoomla]

Hello, we have a joomla website that does not pass the core web vitals test. We are on a shared server hosting and the server response time is 3-3,5 seconds. Any suggestions about a new hosting plan, ideas for making our joomla website faster? Many thanks in advance.

Plenty has been written about this already. If you google 'optimise/speed up joomla site' you'll get plenty of detailed answers. What works for you depends on the particulars of your website (including hosting and components used) and will require some investigation into what is causing the slow down in your case. Some measures are a matter of reconfiguration or patching, others are system plugins that combine css/js. Moving to a VPS or dedicated server usually helps too, budget allowing.
If you're unsure, there are also services that will analyse your site and implement changes to speed things up. If you go down this route, ensure they are promising to optimise a Joomla site in particular.

if you are on plesk or cpanel swap your php handler to PHP-FPM and this will reduce time to TTFB.

it is mod_php that is slow.

also caching will speed things up but that is a bit of a cheat.

lastly make sure your site is https and your server is http/2 capable

Enable OP cache in php. That will speed up execution time.

Do you mean enable this on the server? or have I missed a setting in php.ini?

Starting with optimal hosting configured specifically Joomla really helps. Someone mentioned that caching is kind of a cheat, which I’m not sure why one would say that. Squeezing every bit of potential out of optimizing your site isn’t cheating. It’s smart because it benefits your users, which is strangely what Google also cares about in terms of your page speed scoring. We’ve moved all of servers over to LiteSpeed to ensure all of our customers enjoy the added optimization benefits inclusive of the LiteSpeed’s Joomla caching extension for their sites.

Disable JCH Optimizer or at least reduce counteractive settings like HTML/CSS/JS minification. Stop generating CSS/JS files on each load.

Yes that is also good advice though I never get JCH Optimzer to worka good unfortunately.
