Does figma load every page in a file at once?

I can swear I’ve seen figma tutorials where it seems that one page in a file loads at a time - But when I open my files it seems like the whole file loads at once?

And it’s slow!
I’d like to consider spreading my designs out over more pages if it helped any - but I’m not sure it would??

Anyone know?

If the issue is performance and the lack of memory, indeed splitting the file into pages won’t help. Your only option is to split into separate files. If the issue is simply loading times for the file when opening it, multiple pages help a bit as they are not all fully downloaded at the same time, especially the images in them.
