Beta 7: Content Builder with Dynamic content a lot slower?

Beta
#1

Hi!

I have the same site both on production and staging. I have noticed that certain actions like adding new sections or even scrolling are a lot slower in Beta than in Pro 3.2.3.

This is happening only on some pages. It seems like it has something to do with existing multiple dynamic content.

For example, if I change something at the top of the page, and then add a new section at the bottom, all rows and some elements will be selected by themselves first—one by one, and only then the section will be added.

The rows and elements that are getting selected by themselves one by one are those between the section where I did the last edits, and the bottom one I have just added. It sometimes waits for more than 10 seconds for all of them to appear selected before the new section gets added.

Here is the video. The self-selection happened on my second try:

Thanks!

Thanks @Misho, checked into this and it looks like there’s some room for improvement on making that faster. When using a Looper, if you change an element somewhere inside that Looper it renders all the elements in the that tree. What shouldn’t be happening (but is right now) is that adding new elements outside the looper triggers all the loopers on the page to re-render. Solving this should get us back to where we want to be performance wise.
