This confirms my understanding of Zope and Python. ZEO does not solve your problem explicitly because ZEO is more of distributed way of balancing the load. This is another ball of wax and ,in theory, it works great. But it has its own particular problems. Until someone conclusively shows, our build of Zope server is based on single CPU. We would rather spend more time making Zope more fault-tolerant through use of journaled file system and high availability. Our experiences of supporting large sites have pointed in this direction.
