I think that the dumptruck to pickup trucks analogy works here. Entry level on an AS/400 can be like that dumptruck -- you don't need such a large machine and it costs too much. And even in large companies new technology often isn't planned from a big picture perspective. Project by project it may seem cheaper to add another pickup than to invest in a bigger machine. I guess what we're looking at price for performance vs. scalability. You can start up an NT server based web application for much less money than an AS/400. These days NT servers will scale very well, giving you fine CPU performance for little money. As you cross the scalability limits the costs for administration on multiple servers and to maintain stability will make an enterprise server more cost effective. I don't think IBM's delay getting the faster CPU chips into the iSeries is a deliberate financial strategy. As I've stated before (it's one of my favorite soapboxes) IBM will continue to fleece 5250-based customers through Interactive Feature ("Money for Nothing"). -----Original Message----- From: Nathan M.

If someone says their Web application offers performance comparable to a 5250 application, they're taking big liberties with the word "comparable". In my experience, Web applications use 5 to 40+ times as much CPU time to produce an HTML page that contains the same data you might find on a 5250 screen. Even for pages that don't contain images. It would be interesting to examine the reasons for this observation. But as it relates to the issue of price vs. performance the answer is that Web applications need a machine with a fast CPU that doesn't cost an arm and a leg. Is the reason for IBM not putting fast CPUs in the iSeries because they think it will erode their income from customers who use the machine for traditional 5250 work? I've heard similar lamentations from Domino developers. They like the idea of server consolidation, but they run into the problem of price vs. performance. Comments?
