Forget it. I actually was talking about memory, not disk space. But the 
data gets loaded into memory anyway, whether you use caching or not, so 
that doesn't make a difference. The disk space is negligible.

I actually expect an even higher performance gain, because when I did 
some profiling recently, the registry instantiation was one of the hogs 
on light or highly optimized pages.
