I am pretty sure that is why it was implemented in the first place.
The KDE system config cache contains an easily accessible (mmap'able) binary 
form of the values contained in text based system config files.

There are additional other caches, such as a cache for icon pixmaps.

Thes caches are, if I am not mistaken, not only used by the desktop but by all 
applications using the respective access libraries.

No idea, but sounds plausible that they have implemented some form of caching 
as well.

If you need more indepht info on KDE's caching I would suggest to direct such 
questions at the kde-core-devel mailinglist, where most of the KDE 
infrastructure developers are subscribed.

Cheers,
Kevin
