Without knowing the app I'd probably say there are many ways that it can
be made more efficient. For instance are your image urls being generated
using Zope's acquisition? If so, don't do that. Another alternative is
to move the static/fluf images out of zope and just let apache serve
them. That's just small thing that you can do to reduce the load on
zope. Things like squid, zeo, better hardware, re-analyze long running
routines, etc are all possible without having to do the other gymnastics
that have been discussed.
