bug#2717: 23.0.91; Poor performance of flyspell + HTML mode

wget  http://www.thelatinlibrary.com/caesar/gall1.shtml 
emacs -Q gall1.shtml [the HTML-mode should be activated]
M-x flyspell-mode

try to navigate the document with C-n C-p, C-f C-b, you'll notice that
the delay is often huge and emacs become inusable for a normal editing.
The C-f seems (but I believe that only seems) the most problematic.

The performance is poor without X, too.

Bests
