Originally we wanted to drop support for zope.server over twisted, but it 
turned out that zope.server was much more stable.

We played with it a little bit and got it working without any hassle. But we 
did not test performance.

I think the server itself is not really creating the bottleneck. What you 
really want to do, is keep your transaction times in Zope very small, like in 
the 100ms range, because a Zope thread is blocked for that long. If you have 
queries or tasks that take a long time (>1sec), then you should  run that in 
a thread/process that does not block the server. A good package to start with 
would be lovely.remotetask -- I hope that we will soon release an extension 
that allows you to scale it better.
