This only helps if your pages are mostly static, or mostly the same for
each user. Many/most of our pages are highly dynamic, this makes a front
end cache a bit exciting. For RAM caching, we use a whole pile of different
values as keys - languages, partner, that sort of thing. The sidebar on
www.ekit.com is ram cached - right now, the ram cache has 320 different
sidebar entries.

Other things I found that helped (digging into the memory here):
  avoid dtml-tree. It _seems_ neat, but it's a total time sink.
  work out which SQL methods are getting hit, and when, and cache
    them.
