Didn't know it's possible to do arithmetic on bug numbers ...

Following the recipe from bug#2717 on GNU/Linux shows a slowdown for me
too.  
If instead I do (as suggested in some other bug):
emacs -Q gall1.shtml
M-: (setq process-connection-type nil) RET
M-x flyspell-mode RET

then the cursor movement is much better.  Not perfect, but still better.
