There are some packages that cache the results of python functions 
calls. In Plone, plone.memoize is used often. There are others like 
bda.cache and gocept.cache. For these caches to work you have to 
decorate the functions you want to call.

Like Andreas said find out where your bottlenecks are before you change 
things.

You can take a look at the Zope configuration. To small zodb connection 
caches decrease performance due to unnecessary unpickeling of objects, 
to big settings or to many threads can make the operating system swap.
