Trunk's about the same as Emacs 24.3.
On my platform (configured as in my previous message), running this:

src/emacs -Q -f global-font-lock-mode src/xdisp.c --eval "(let 
((c-standard-font-lock-fontify-region-function 
'font-lock-default-fontify-region)) (font-lock-fontify-buffer))" -f kill-emacs

took 47.2 s with Emacs 24.3, and 44.7 s on the trunk.
