I believe it was (maybe still is) a problem on the Zseries..  They (IBM)
created devices to actually offload telnet traffic because it could
cause an added burden on the system.

The problem with telnet, as I understand it, is that it is character
based.. Not screen based.  It was developed for unix, which needed to
see every character as it was typed (vi editor), and not a "screen at a
time" (3270 data stream.   So sending the mainframe every character
(which comes in the form of a TCP packet) from every user (which on
mainframes could be 100s to 1000s) as they were typed... All of a sudden
the cpu resources to handle VTAM/TCPIP skyrocketed.

Anyway... A company the size of baxter probably has some old timers that
recall such problems.. (and, in all honesty, may still be real
problems).  We don't have enough users to worry about it.

------------------

There's a big snit here at Baxter about using telnet-- there's a claim
that telnet uses more system resources than passthru... I've never heard
any such claim before.  Is this one of those things that was true at one
time? (Also, I can't get anyone to be specific as to which resources are
being
hogged-- comms, CPU, etc.)

Thanks!
