It's also *swamped* by the memory and CPU savings of ripping out
NetworkManager by the roots, and deleting or disab ling most of the
quite bulky Gnome or KDE toolkits for most users. Pulling out the
language packages, most of which are entirely unused by anyone with a
formal education, is another profound savings in system resources,
including languages for those packages that enable the installed
languages.
I do a great deal of work in small virtual hosts, and eliminating or
refusing to use unnecessary graphical or language toolkits is a
profound resource savings.
