RE: Green-screen versus browser

["Joe Pluta" <joepluta@xxxxxxxxxxxxxxxxx>]

This is simply NOT TRUE.  A properly designed web application written
primarily in RPG with a JSP interface can deliver response times very
nearly equivalent to green screen -- and certainly far better than the
"significantly slower user response time" you state.  On a LAN, browsers
provide sub-second response time, and usually the same on all but the
slower WANs.  Even with dial-up, a well-written JSP application can
provide a response time from 1-3 seconds.

As to the concept of "heavy iSeries resource usage", this too is a
misnomer, though with a little more factual basis.  A proper WebSphere
installation will require about 500MB of dedicated memory.  While not
cheap on the iSeries, it's not prohibitively expensive either.  And if
it is indeed too expensive, the WAS portion can be offloaded to an
attached dedicated PC.
