Database + apache + a lot of fairly large FastCGI php processes -
which surprisingly don't use superpages.

PostgreSQL, apache, php, dovecot, spamassasin, python web apps, and a
lot of other things - I'm sure you can conclude from the list of
processes.

I'd like to learn more - can you post the results from your own server?

Yes, except for postgres which is used rarely, it's a fairly typical
KDE desktop.

Yes, a survey of three machines means nothing. I'm looking for more data.

If anyone posts more data, I'll analyse it. I'm more worried about the
granularity of procstat, where it marks the entire region if a single
superpage exists in it - it means any such analysis is only
approximate.
