Unlikely although Python 2.3.3 is a bit faster than 2.1.3. Btw. we are 
currently
at Zope 2.7.2+

Why two instances? Why don#t you pack everything inside the same instance.
To speed up things:  don't run Zope in debug mode. get a fast cpu, get 
enough ram.
use caching. profile your application. there is no general how to speed up 
zope.
often the application design and implementation is just bad. use 
ZopeProfiler
to find out bottlenecks. And consider kicking the windows plattform.
