That's true.  It has surprised me to hear a number of people say that they
thought the OS/400 HTTP server might be a bottleneck.  But when you start
doing timings, the performance problem lies either in the backend
application, or the application architecture.

IBM's has been emphasizing how the performance gap between Java and RPG is
getting slimmer.  So, we RPG enthusiasts may get carried away and emphasize
any advantage.  The important thing is that whatever architecture you
choose, it needs to produce applications that are functional and
maintainable.  And it needs to enhance programmer productivity.  That's my
focus, and aparently your's too.

You seem to be going in a completely different direction than I, by creating
components to generate formatted output (HTML, XML, etc.).  The direction I
took was to leave the format of the output entirely to the HTML or XML
author.  I just want to efficiently insert application data into a formatted
template, and send the result to the client.
