As a sub question to this (and to possibly save some 'fiddling' time) what
would generally be the optimum set up on a server with 2 x Dual Core
processors

2 zeo client with 6 threads
3 zeo client with 4 threads *
4 zeo client with 2 threads

I would try 4-6 ZEO clients with 1 thread each first. Again, the reasoning being that your OS is better at scheduling processes than Python is at scheduling threads.

Object cache for each zeo client will be 40000.

Yup, make this as large as possible, and if you have a separate mount point for the Catalog, it can keep it all in memory easily even on large sites, which helps performance significantly.

I understand that each use case may be different but in terms of best
practice when optimising, what would one normally expect to produce the best
(caching/ rendering time) results.

Right, there are lots of variables involved. I'm trying to nail down some rules of thumb for a "performance tuning basics" manual on plone.org.
