[Zope] Setting up a dedicated Zope box

Depending on the type of site it was (writes are much more expensive 
than reads in almost all contexts), and how well the code was written, 
I'd imagine that a single Zope backended by ZEO could crank out on the 
order of 30 - 90 r/s.  But the ZEO server isn't the bottleneck here, 
it's Zope.

The ZEO server I mentioned that spikes the processor is fronted by 10 
ZEO clients, but each appserver is only capable of delivering a nominal 
7 requests/sec due to a lack of app optimization.  After caching, the 
ZEO server ends up servicing somewhere on the order of 5 transactions 
per second or so during normal load, but I can imagine that it's serving 
about 5X that number during peak periods.
