I guess it all depends on your position: if those 10% more memory
imply that you start thrashing, you probably prefer 10% less memory
usage cause those 10% "speed" increase won't be noticeable. As a
user, I prefer a program that half the size to a program that twice
as fast in most cases: most of my programs are "fast enough" (I'm not
doing using any kind of CPU-heavy programs: only a window manager,
text-editor, mail reader. Even my LISP compiler is fast enough when
compiling and it's too slow to be interactive when I test my programs
(which are slow because of algorithms which haven't been tuned yet)).


I care a lot more about other users running big LISP jobs than about
other users leaving a broken emacs take 99% of CPU time (as you can
see, I'm not using much of my CPU since there is often 99% available
to a broken process). The only noticeable effect of a CPU-bound
process on my environment is my background animation getting slower
:-)
