Is this in "emacs -Q"?
Not in my case, although I'm using the same setup in 22 and 23.
Anyway, is the slow-down you see close to the OP's reported factor of
almost 3? Or is it just slow-down?
Note that the most dramatic changes are due to my header line (tabbar)
and also face remapping:
(setq face-remapping-alist nil header-line-format nil)
(NB, I have backported the face remapping functionality to 22, so I
believe am comparing like for like.)
Without face-remapping and header line, I estimate the slowdown is
about 20% for me, a noticeable difference.
