Some companies map certain session names to certain subsystems. For
example, if all of one divisions session names begin with D01, and then you
map all of these workstations to another subsystem, you can then end that
subsystem to keep them out during critical times. However, if you've made
a mess out of tuning that other subsystem then you can have problems. That
is what I was trying to get to. Sorry for the confusion.
We use TCP and almost no twinax. I don't see the reason for the
discrepancy in the response time which you are seeing. We might still have
some SNA PC's out there. I know that there was a mode issue with those.
Seems like your comm came in, (before you got to 5250), a lower mode and we
had to change that.

Yes. I do believe that this would be the case. Are you getting at
something? Why would this matter? Again, ALL 5250 terminals are OK under
ALL circumstances. ALL PC's communicating over tcp/ip are affected by this
slowdown.
If there is anyone out there using tcp/ip? Do you generally see improved
speeds vs twinax?
Thanks,
Keith
