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?
