Interactive Response Time

["Jon Paris" <Jon.Paris@xxxxxxxxxxxxxx>]

 >> Also found is that there is a big difference between machine response
time (as measured by timers in the code) and user perceived 'wall time'  as
measured by looking at the clock on the wall

This reminds me of something we found some years ago during testing with
users.  Their perception of the response time also had a lot to do with when
they first saw something come back on the screen.  Users at a remote site
who saw their screen start to fill up after about 1.5 seconds (but didn't
see the complete screen for 4 or 5 seconds) were happier with the response
time than local users were when they had a completed screen in 2 seconds.

Perception - perception!!
