Hi,
I am sorry, but you don't see the amount of time required for loading the page?
Just look at the attached screenshot, it's clearly a heavy load on the page when using dynamic content.
Also check the page speed report.
I expect the page to be more dense when using dynamic content, but not this much.
Maybe it has something to do with the fact that refereces were used? Other dynamic content pages without reference load 2-3 times faster.
If you say there's nothing wrong, alright, I can accept this, but the reports do not lie. I am just trying to help make sppb better, I can go on without the dymanic content to be honest, but it's a very good feature and it would be a shame to not be able to use it because of its heavy load.
