Yes, xfce4-terminal is a real memory eater, also libvte9 makes
gnome-pty-helper tread every time a terminal is opened this is also not
very nice. Not much I can do about this problem, because I seem to be
the only person caring about it.

I indeed don't use gdm but compiled a automatic login command. I like it
that way. It's for an one user workstation, so its ok for me.

Due to the memory model of Linux and its caching system, it's a bit
tricky to connect memory use with performance. However it does say
something about the needed memory for an application to be able to run.

Kind regards,
