Any load balancer should be able to do this, google for your OS there. The load balancer I use LVS. See http://www.linuxvirtualserver.org/ for more details. Andrew Sawyers -- Zope Managed Hosting Software Engineer Zope Corporation (540) 361-1700

I did some tests a few years back, basically that came out such that you run the number of zope instances as you have CPUs. I was able to get double the performance of a single instance on a dual cpu server when adding a second instance. On a single CPU server, I found that the number of requests the server was able to render was cut by nearly 50% +/- when adding a second instance.
My rule for building out ZEO Client servers is: Single CPU - Single Zope instance Multiple Processors - # CPUs == # of Zope instances
Hi Andrew,
And how can I distribute the load over these Instances, running on the same machine?
Thanks in advance.
