In that case (and in that case only) it is much better, from a user viewpoint, to wait say 20 seconds before the file is opened and being at that point able to freely move through the file, instead of waiting only 6 seconds, and then having to wait another 10 seconds between two motion commands like M-> C-p. In fact, no user expects that a 1 GB file would open instantaneously.
