Hi
after many trials and errors also with JCH optimize before that maybe latest version working well, I can recommend JSpeed plg if you want tro speed up your site. It have a lot of settings and you can customize it for your needs.
https://storejextensions.org/extensions/jspeed.html
Only one JBD listing issue and setting is that you have to do this:
HTTP/2 settings - Enable HTTP/2 Server Push - Assets types - Disable-->image
*** Disable the image asset type bcs it doesnt work with JBD listings at least not for me. I guess there is some lazyload, cache etc for JBD listing menu issues there but working well with offers, events menu listings.
I have also been talking with them about this plugin.
I asked what template works best with JSpeed and this was the reply I received:
"Anyway, it's important that the template chosen is as light as possible and not too much based on Javascript and CSS effects."
I am using Helix Ultimate 2.
It works fine but it is buggy likely heavy.
Kind of wondering if there is a better option for top performance?
On their Facebook, they have websites clocking a Google PageInsight scores of 99.
What template are you using?
A clean Helix Ultimate v 2.0.6 with Bootstrap 5 and SP Pagebuilder Pro Helix Ultimate v 2 by Joomshaper
Same as me.
Anything faster?
I think Its a tradeoff to have easy good many design elements with a template framework or redesign a fast clean std Joomla Cassiopea template as option.
Other nice template frameworks is Joomlart T4 https://www.joomlart.com/t4-framework free Purity is fast but not updated yet https://www.joomlart.com/joomla/templates/purity-iii and Yootheme Pro with predesign styles similar like SP Pagebuilder imports https://yootheme.com/page-builder
I think yootheme has the best design feel bcs its german guys I think that doing that on Sacha. I tried the old version long long time ago and it worked ok but now I think its really nice with new Pro version...
I dont know who is better regarding performance bcs that also depending how you build your site of course..
With SP Pagebuilde you can do a lot https://www.joomshaper.com/page-builder/features
