Uhm, if you have so many kdebug calls that this is still a noticeable
overhead you did something wrong with kdebug (i.e. used in far too many
places)

See kdelibs/kdecore/kdebug.areas and/or run kdebugdialog. All larger
apps and nearly all libraries in kde have one or more so called debug
areas so that one can individually turn off debug output that one
doesn't want to see. 

In the code you use kdebug(<somenumber>) <<... to specify the area and
when you deselect it in the kdebugdialog you won't see any of that
output (I don't know the implementation but it seems it just goes to
/dev/null or some such, i.e. really fast)
