Performance on Windows (msysgit) with latest patches

Hi,

After all the performance patches that has been commited to the git.git/master branch, I figured it would be interesting to check out how it would affect times on Windows. So, I merged the git.git/master branch into the 4msysgit.git/next branch and ran the scripts which Moe provided. The result you'll find below.

git-status got a 1.6X speed-up, and git-commit on a single file got a 2.5X speed-up. However, git-add and git-commit of all 100K files got a slight slowdown.
