Mike--The answer is "it depends" (Bill Bitner) but that answer is also
contained in a paper I wrote in about 1970 while working on my MBA at
the University of Chicago. It was entitled "Psychological Aspects of
Terminal Response Time" and it earned me an "A" for the course.
It really does "depend". I'd love to send you a softcopy but it was
written before I could have saved you one. I have a typewriter written
carbon copy.
An important element that goes into this is the expectation of the
user. Consistency is important as is the perception of the difficulty
of the task.

We've determined an average workstation latency (simply using PING) for a
workstation "far, far away" as being about 380-400ms.
But we don't know what it would be like to actually WORK on that
workstation day-in and day-out. Most of the work would be in support of
Linux for System z servers. Most likely via SSH (using SecureCRT from
VanDyke Software), but also some 3270 usage, net surfing, and Lotus Notes.
Does anyone know of a way to set a reliable minimum or "min-max range"
latency on a given workstation so that effects on productivity can be
measured?
