No, I haven't. But I still don't understand what the big deal is.

Here is the memory usage on my fully updated ("install everything" and
more) 64-bit FC4 on which I am typing this email:

          total       used       free     shared    buffers     cached
Mem:       1020000     464112     555888          0      35580     276324
-/+ buffers/cache:     152208     867792
Swap:      2097144          0    2097144

Used memory minus buffers and cache - 150MB. This is with the normal
(for workstation) services running + sendmail + KDE3.5.

And here is another computer I have at home - totally obsolete RH7.3
on a PIII:

Mem:        126308     119696       6612          0      79992      27252
-/+ buffers/cache:      12452     113856
Swap:      1020088      27752     992336

(it is not doing much at the moment, I grant you, but it looks very
happy with 128MB of RAM).
So, I really don't think that Gentoo has a monopoly on
efficiency. Yosef does not badly at all until he starts Matlab, or so
it seems to me.

You're right, but...

I just checked the box at my parents' house that's still running Gentoo. It has a pretty close configuration, and it runs the same processes +- (no hald, but with Samba and [EMAIL PROTECTED]). free reports only 91 MB used (not counting buffered/cached). that's 60 MB less! I don't need them to run my lungs, but it's still a big difference! And X is installed with most use-flags on.


So why not use top, ps et. al. to see who actually consumes this memory?

I've already seen that X is the main hog before. Now that I'm near a Gentoo box I compared the X config and found that the Kubuntu X runs some extra modules - GLcore and some others. Sure enough, removing them freed up a lot:
            total       used       free     shared    buffers     cached
Mem:        247604     238144       9460          0      16284     118668
-/+ buffers/cache:     103192     144412
Swap:       249472      21872     227600

This with Thunderbird composer open. It seems that Gentoo really has no monopoly on efficiency.
