It's the new non-backtracking regexp engine at work (see ":help
new-regexp-engine"). It's supposed to be faster than the old one for
complex patterns, but in practice it can be 10+ times slower for things
like syntax highlighting. :) You can turn it off completely with
set re = 1
If you have a file that illustrates pathologically slow highlighting
you might want to post it to the vim_dev list, so that the few
masochists who haven't turned off yet the new engine can analyse it and
improve the syntax patterns. Upgrading the runtime files from Mercurial
does help somewhat, too.
