I don't have this problem at all (perhaps because my agenda files are
puny at less than 5K lines total), but I obtained a profile[fn:1] and
most of the time goes to font-lock stuff. Here are the top five:

font-lock-fontify-region                                      11953

What does your profile look like?

Thanks,
