[Zope] Zope.org performance

I see such large amounts of memory here as well -- when I have
a 60M database and just two users (it's our demo machine).  The
OODB contains 30 directories of 20 files each of 100 KB text.
When we fire up /manage and peek into one of those dirs,
<wham> up goes the load, until I restart the server and then
it drops down to nothing.

Oddly, accessing the site via FTP seems to place little load,
so I presume the Zope persistence mechanism is reading
into memory the entire content of each 100 KB object, just
to present it in a list on the manage screen. (?)

We're looking at switching to placeholder Zope objects
and storing the text as static web files outside Zope.
