Yes, it does stat all the files. How many files are you talking about,
and what platform?  From a warm cache on Linux, the 23,000 files kernel
repo takes about a tenth of a second to stat all files for me (and this
on a several year-old machine). And of course many operations don't
require stat'ing at all (like looking at logs, or diffs that don't
involve the working tree).
