There have been a couple of optimizations that are probably still not
enabled by default because they only benefit large repos. So you may
want to check and turn them on before measuring anything:
commit-graph, pack bitmap, untracked cache or fsmonitor. All these
should be mentioned in 'git help config' (as starting point). Also
search "threads" in that man page because some commands may have multi
threads support but disabled by default for the same reason.

(maybe with a bit faster 'git status') even with all optimizations on.
