It is, indeed.  But here we are talking about big files (say 1 GB).  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.
