Booth,

I agree that there is a change in the paradigm.

To compare apples to apples, get one AS/400 to echo keystrokes, get
another to file serve, get another to application serve, get another as
a communications server, etc.

To have 20 people keying into a chat session and 200 others lurking does
not put the same load on a server that has 200 people doing order entry,
cash receipts, payables entry, production scheduling, shipping,
receiving, inventory control, payroll, etc.

IMHO, one of the failures of OV/400 was the performance degradation when
you had too many people choking the system with keystroke activity.

The shift in paradigm may be to blast the file down to the client
machine and let the client handle file positioning and keystroke
echoing. And the GUI.
