So I just had a quick Hangout with a Wix Show member and trying to help him. What I have realised is that is seem that repeaters connected to datasets are way more slower on the published site than if you call a backend function using Wix Data and retrieve the items that way and setting the data property to the received items.
Can anyone from the Wix Code team say anything about this please. I know people use Datasets and Repeaters because it's so powerful, but if the difference in performance is that high that I think it would be good for a tutorial on how to code this in the backend.
I guess all backend code executes exremely fast and page code doesn't so that's why I am asking if you know it is faster doing repeater data connections between backend and frontend instead of using the datasets.
