[Zope] Low Cost Linux Web cluster? How? - Performance

[Brad Clements]

I've been using Zope on various customer deployments .. all on low-end PIII Linux 
machines.

One customer is growing .. to the point that we'll need a database server (going to 
move from Interbase to SAP DB), and one or more load balanced "web servers" 

We're planning to use mod_backhand (spread) or something like it to distribute web 
requests to ZEO clients on multiple machines.. 

I'm looking for suggestions on hardware selection and architecture for a growing OLTP 
type web backend. 

Also, was planning on converting all my DTML to Page Templates, but some of the PT 
stuff completed thus far is compute intensive and not very fast.. I'm still trying to figure 
out why (Zope 2.5.0)  with PT 1.4.0

I'm thinking of converting to XSLT with Sablotron -- and if an IE client connects I'll send 
the XML/XSL to the client instead of rendering on the server. Anyone have war stories 
to share?

Thanks

(my first Zope E-Commerce site is still chugging along well on it's single machine.
