Windows 8 added several fonts that are very large and cause slowdown
of the Emacs redisplay.  You can discover those fonts by moving the
cursor around in the buffer and watching for slowdown; then installing
alternative fonts for the same scripts will make the time much
shorter.  Start by installing Symbola, if you haven't already, as the
default Emacs fontset tells to use it for some Unicode blocks.

When you do that, the fonts are served by your local X server, which
runs on Windows, right?  Then I'm guessing that the X server already
has the fonts loaded since the last session of Emacs or other
programs, so the comparison is "unfair".

It takes 5 to 6 seconds on my Windows system to display etc/HELLO,
when I start with "emacs -Q", FWIW.
