---- Usability: How many page loading seconds are acceptable?
FBIB of 2 to 3 seconds is long. If I encounter such a website my mouse is already hovering above the back button when the screen is white for more than 2 seconds. A few years ago I wouldn't have had any problem with waiting 15 seconds for a page to open, but I now expect a remote website to open faster than my local word-processor can open a new document.
Besides the FBIB there are some more statistics interesting for your pages:
