Yes, expectations differ widely :-) For me anything above 1 second is 
slow and needs improvement. Anything above .5 second is bearable but not 
ideal. This is bad habit from PalmOS and old days when computers were 
fast :-)

There is some old paper on the net about KDE performance by Waldo 
Bastian, see also [1]. Here is the relevant part: "Slow is a very 
subjective term, but when it comes to a graphical user interface, things 
are typically perceived as slow when there is a latency of more than 0.3 
secs. between action and reaction. So if I click on a button, it should 
bring up a window on my screen within 0.3 secs. If it takes longer, 
users tend to perceive the system as slow."
