    I've noticed that entering a Git controlled project directory takes
    quite some time so I wanted to measure exactly how much (it's the
    prompt I'm using that's taking the time, I suspect). I first tried (a
    bit naive, I admit :-) )

    time cd my-project

Your confusion is because you are measuring the wrong thing.  I'm
assuming, here, that you have a shell prompt which is giving you all
sorts of status about the git repository.  The "cd" operation is
instantaneous, it is the shell attempting to compute the new prompt
which is slow.

Exactly how your shell does this is shell dependent, but you might
want to look at your setting of $PROMPT_COMMAND.  Then you can test it
by running something like:

time sh -c "cd git-directory; $PROMPT_COMMAND"
