When was that last updated/verified?  I think the information there is
mostly outdated.  E.g., the stackoverflow question and advice refers
to Git 1.7.x, and definitely describes a broken setup ("cd" taking 8
to 25 sec? come on, be serious!).

The only factor I'm aware of for slow startup of Git on Windows is due
to MSYS Bash and other MSYS commands that are run by those Git
commands that are implemented as shell or Perl scripts.  MSYS is a
fork of Cygwin, which is known for this issue (emulating 'fork' on
Windows is expensive).  Git commands that don't invoke Bash or Perl
should be fast enough on Windows, AFAIK.
