I agree. Most of the web surfers I run into are pretty impatient ...
if a site doesn't load pretty quickly, they're off the next and have
forgotten about it.
A few years back, I attended an indepth demographics survey - very
interesting - one of the many things covered was how the time to click a
mouse while surfing the web had become a 'time standard' for one group
of the younger generation and you would loose their attention if the
response to the mouse click wasn't rapid.
For web viewing there really in no excuse for excessively large image
files. I try to keep my posted images around 100 KB unless a bigger file
is required.
The general rules (empirically derived from user testing) are:
Anything under 0.1 seconds feels "instantaneous" for all practical purposes.
1 second is the maximum time delay allowable that lets the user feel
they're sufficiently in control of what's going on.
10 seconds is the limit before it's advisable to display a "progress
bar" of some sort.
This is Nielsen/Norman research, as usual.
