It probably has nothing to do with KDE - its depends on your video chip driver 
and whether it supports video acceleration.  This is where I suggest you 
concentrate your efforts.

First area to look is have you installed debian package xlibmesa-dri - but 
beyond that you will also have to check that correct driver is being used and 
X is not just falling back to use the default VESA settings of your video

This is nothing to do with video performance, rather start up performance (by 
prelinking libraries so it does not have to be done dynamically at the start 
of each program.  

As far as I am aware, the later releases of the GCC compiler do this anyway - 
and therefore the standard debian packages available in SID now are as good 
as it gets - which actually is pretty good compared to anything else.

Sometimes the odd server is useful - sshd allows you to connect in when all 
else fails (ie when X locks up - as it does occassionally).

Again - really no point in compiling your own.  The debian packages are all 
available for different classes of hardware - and have all the drivers that 
you need as modules.

I think you gain a lot more in general compatibility with debian, its package 
update mechanisms in particular,  if you stick with the standard packages 
rather than try to build your own.  I really don't think you loose anything 
in performance.
