Using kdeinit4 to launch KDE applications makes starting a typical KDE application a couple times faster and reduces memory consumption by a substantial amount.
kdeinit4 is linked against all libraries a standard KDE application needs. With this technique, starting an application becomes much faster because now only the application itself needs to be linked whereas otherwise both the application as well as all the libaries it uses need to be linked.
The process name of applications started via kdeinit4 is "kdeinit4". This problem can be corrected to a degree by changing the application name as shown by ps. However, applications like killall will only see kdeinit4 as the process name. To workaround this, use kdekillall (from kdesdk/scripts) for applications started via kdeinit4.
(Prelinking is a process that allows you to speed up the process of dynamic linking.)
