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).
