I just sent a message explaining what happened to this list.

My current tracking shows that is pretty snappy until the
server gets attacked from a bunch of spiders.  Because has a
huge quantity of pages (500+MB of (packed) content and climbing), and
because objects get loaded into ram as they get accessed, accessing
*everything* on the site multiple times causes zope to load things in &
out a lot, causing it to slow down.

IOW, if you have a zope running with, say, 100 mb of content (that's
2048 50 kb pages) on a box with, say 256mb of ram, and you have your
caching policy set very liberally, then you should be able to hit 30
requests per second, or 2.5 million hits per day. will be on hardware that stretches the notion of "commodity"
soon, but it will be sufficient such that all 500mb of our objects can
be floating about in ram if need be.  This should improve our
performance drastically.

Hope that helps,
