I'm not surprised you can't spot any difference just by looking at the two
technologies - At a single user load, the timing differences will be
microscopic. You would need to be load testing with a few hundred users to
really notice much difference.

IMHO a well written Servlet/JSP app, making good use of connection pooling,
should be at least as efficient as an RPG/CGI app, and a lot easier to
maintain. Via stored procedures it's easy to access back-end RPG code, if
required.

This is a V5R1 on 9406-270 box with 1 G RAM. I don't know how to look up CPW
number. If you let me know I will get it for you.

Servlet runs on any other platforms too. I copied the same application to a
Linux box and have the application access db2 on the AS400. This linux box
is a P5-110 (one can get for $30 from ebay). The performance is good. I hope
you can see it over internet. (I access it in LAN using a different IP).
