I'm unsure if this is the right sub forum to ask this, but how does total imported file size affect loading times? In other words, how many MB can you put in before it makes a significant change to the load time?
edit: I tested this with a 22 MB file of models and textures via the test document function, and 44 MB file with the same setup. They both took the same amount of time, down to the second. Go figure.
edit2: I tested online with 2 accounts from the same network, with 22 MB and 50 MB, and the difference was about 3 seconds.
