From: Michael Haggerty <redacted> Packed references are stored in $GIT_DIR/packed-refs sorted, so adjacent ones are pretty likely to be in the same directory. So while reading them, keep track of the last directory used, and reuse it if possible to avoid searching the reference namespace from the root each time.
