Does the "find" command cache file system info?

I'm curious about this observation: If I do a find search on the root 
directory, it ordinarily takes a minute or two -- as one would expect if 
it were examining everything afresh.

But if I follow that up with a different find search on the root, it 
finishes in a few seconds.

Does find cache file system information and reuse it under certain 
conditions?  Or does Linux itself cache some sort of information from an 
initial search that a subsequent search benefits from?
