Okay, what I'm getting from you now is that you think loading any GUI program 
in Linux is too slow... not just KDE programs.

You are right.  Compared to, say, Windows, Linux is *much* slower loading and 
starting applications.  You don't really notice it when you load command line 
programs since most are quite small.  You do notice it with GUI code because 
even the small ones have huge libraries.  This takes quite a bit longer 
because the Linux loader is very inefficient and the more symbols that need 
to be resolved, the longer it takes.

There *is* work being done at the system level to help alleviate this 
problem.  I don't know when the time to delivery is.

On the KDE side, we've tried to jump start this process a bit with some local 
hacks.  For instance, most KDE apps are started with the 'kdeinit' process 
which already has the KDE libraries loaded and resolved.  This saves the 
linker a *lot* of time compared to loading the libs from scratch.  There is 
also the experimental "objprelink" code with tries to resolve all the symbols 
at compiletime.  This results in significantly faster startup times.. at the 
expense of stability.  We've had a lot of reports of crashes with objprelink.
