    I've noticed that entering a Git controlled project directory takes

    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"
