Good morning,
On all my websites I use Helix Ultimate as a framework + SP Page Builder Pro to build the pages. I am now working on a website that must load very quickly. The server speed with my hosting provider is good, so it is not that. I tested through Google PageSpeed Insights, where I get a very low score especially on mobile, while mobile is the most important thing nowadays (mobile first). Then I also tested the JoomShaper website. This website also has a very low score for mobile (43/100). Desktop scores well (95/100).
I tried JCH Optimize to optimize pagespeed, this helped a little for desktop score, but not mobile.
Are you aware that the combination of Helix Ultimate and SP Page Builder Pro is slow? And if so, is your development team working on optimizing this in the short term?
Should you think it has some other cause, can you help me further to get the website in question quickly on both mobile and desktop? (See Domain).
