BTW also consider that there are a number of styles in which characters
can be displayed by a terminal and some (e.g. line-by-line) are
forgivably not guaranteed to be as fast as others, since their usage is
slightly different. For example, displaying 'full screen' or 'jump
scrolled' blocks of text should happen ASAP, but character-by-character
output is in some sense "not supposed to be" that fast (hence "scroll
delay" and "smooth scrolling" options). True that most people don't want
their compilation to go slower, though, and it's bad if a terminal
actually displays slowly because it's consuming large amounts of CPU
time. However, I find something comforting in the use of slowish
terminals in combination with GNU screen.

Why is everyone always after more speed!!

OMFG 1 full second??? It takes longer than than for my CRT to switch
resolutions! How did our forebears survive? (Seriously, though: I
realise the point you're trying to make with the comparison to LCD
screens, and I appreciate the fact that developers should not
overlook sources of slowness.)
