If a clicking a button takes 5sec to react with default compiler options. 
With best gcc tuning options you'll achieve 5% reduction in processing 
time, and behold, the button reaction takes only 4.7 sec now!

Slow/Small systems do not really change this basic issue IMHO. However,
you have appeared to change the subject to *size* optimizations, which
I agree *is* important on small systems.

Multimedia codecs and games are ofcourse another story, as well as some
other places, I'm not trying to say that the compiler optimization is
*useless*, just that it often overrated.
