People have a somewhat wrong understanding of what "efficiency" really
means in terms of software. It's not about overall memory usage + CPU
cycles consumed. For example, I can write extremely efficient programs
that require 2GiB of memory and take 99% of the CPU time. So what does
that tell us?
For desktop software people tend to assume that "lightweight" implies
"efficient" or vice versa, but _most_ people don't know how to interpret
(or measure) either of these terms. If you ask them, you don't get
useful answers (as can be seen here); it often comes down to
propositions like "XYZ feels sluggish" or "XYZ takes too long to start"
or "XYZ redraws too slow". Please feel free to prove me wrong and make a
valid, useful statement about how CPU time and memory usage actually
affects "efficiency" and "lightweightness" of the desktop.
If you'd actually read what I wrote instead of just posting the same
crap again and again, which is indeed stupid, then you'd notice that the
real problem cannot be measured in terms of memory usage or CPU cylces.
This kind of non-sense in the OSS desktop community is what keeps me
(and probably not only me) from spending my spare time with Xfce (and/or
other OSS desktop software). This might be benefical for some projects
now (i.e. Gnome devs posting nice graphs about reduced memory usage and
increased performance, even tho the overall desktop feels even more
sluggish than the previous release; and that's by no means a Gnome-only
problem, just serves as a good example), but in the long run it's just a
waste of valuable time.
So be sure to actually read what I wrote prior to starting your reply.
And be sure to read the quoted part of my original mail.
