1) Sorry for my misleading previous e-mail, the 200MB were for
Trinity+system and the 140 supplemental MBs for KDE4+new X server.
I did the tests again just after having uninstalled gtk+2 for the
purposes of the test (I have some python/gtk2 autostarted applets I
suspected of taking up some significant amounts of RAM):
-On console mode (with Intel KMS) the system takes 110 MB RAM (but it
could be better since I use the "huge" kernel, which is basically a
"make allyesconfig" kernel).
-With just KDE4 started, and a Konsole fired up from the Plasma
desktop, the total memory usage went up to 201 MB: 91 MB for KDE SC
4.4.3 + X server (Nepomuk, strigi and KWin desktop effects not
activated).
-With just Trinity started, and a Konsole fired up from kicker, the
total memory usage (KDE4 was exited) went up from 110 MB to 159 MB: 49
MB for Trinity 3.5.13 + X server.
2) Tiago, do you use x86 or amd64 ? There is a significant increase in
memory usage if you use amd64. The system on which I gave the RAM
measurements has x86 userland and amd64 kernel.
3) +1 for the defaults, I don't consider for example that setting the
Oxygen effects by default at "Very high CPU" is sane.
