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

Yes, except for postgres which is used rarely, it's a fairly typical KDE desktop. > As for me, such namings are completely imprecise and such statistics say > NOTHING.

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.
