RE: Websphere: a resource hog?

You gotta love this stuff.  Okay, I just moved the I/O out of the servlet
and into an RPG server.  I still have to start a session with the AS/400 and
call the RPG server program for every request, but this still oubles the
througput.  I'm now matching your response time, Nathan, of about .6 seconds
for 5 users, although I'm kicking out 33% more data.

At this point, WebSphere is running roughly one fourth as fast as your ILE
approach, and I haven't even put the server in batch yet (which will
eliminate RPG initialization time).
