[Zope] performance issues

[Jim Kutter]

OK. So now i'm concerned too.

I have almost an identical setup for Zope (RedHat 6.2, Dual 867Mhz PIIs with
1GB ram) - majority of the content in ZODB. I am running two zope instances,
albiet without ZEO, and my performance is timid to say the least - I've
always suspected it's image heavy pages and excessive use of javascript
(don't ask). But the call profiler reports 1/2 second generation times for
pages on average, the pages take 4-5 seconds to load in the browser over a
T1.

Can anyone point me to how to setup apache to cache zope pages? I am using
proxy passing (mod_rewrite) currently, but I suspect it's not caching.

Redhat Advanced Server seems to have support for this...?
