I have a website with a catalog https://www.unidraft.com/projects-en. On the dynamic page, the photo gallery is connected to a separate database collection. I can't understand the reason why my gallery is filled with photos in one case quickly, in the second case very slowly. The delay can be up to 10 seconds. The size of the photos is not affected.
When the website was in my account, there were no such problems. Could it be the reason that some photos were added to the database from my account, and some of the photos from the client's account?
