dear SAC,
I asked Dan Karran for advice on drupal page caching to reduce load...
"do you have caching enabled for anonymous users?" is the keyphrase.

i bet this would help a lot with the rude-bot-crawling spikes in load.

Hi Jo,
First off, do you have caching enabled for anonymous users? I think
that should alleviate a lot of the pain.
I don't have much experience with Squid, but we do use it here. We
don't have many public sites (most of our stuff is behind Drupal's
login so there is not much use in caching) so we have it set up to do
balancing between different web servers (it doesn't actually cache
anything) and actually I think it's caused us more pain than benefit
in this configuration.
Yes, caching is currently enabled in Drupal on www.osgeo.org for anonymous users. It has a minimal cache lifespan of 5 minutes, but this can be changed.
This is nice because if you are making major changes to the site content, it takes 5 minutes before any anonymous users see the change. So it gives a nice buffer while transitioning changes from testing/prototype into production.
Authenticated users always bypass the cache.
