RE: Web apps on the AS/400

["Joe Pluta" <joepluta@xxxxxxxxxxxxxxxxx>]

We actually just had this discussion very recently, and I posted some very
detailed statistics.  To summarize, on a 416CPW model 170 at V4R4, WebSphere
takes up .6 (that is, 6/10) of a percent of the CPU as a background task.  A
well written web application can serve up a 3KB dynamically generated web
page in about 100msec, as opposed to a green screen application oiutputting
1920 characters (or less) in about 20msec.  For the web app, RPG, servlet
and JavaServer Page time are all included in the 100msec.

Not too shabby.  I have no comparison numbers for a similar CGI-RPG program.
