Ways to improve git status performance

If your git repo makes heavy use of submodules, you can greatly speed up the performance of git status by editing the config file in the .git directory and setting ignore = dirty on any particularly large/heavy submodules. For example:

[submodule "mysubmodule"]
url = ssh://mysubmoduleURL
ignore = dirty

You'll lose the convenience of a reminder that there are unstaged changes in any of the submodules that you may have forgotten about, but you'll still retain the main convenience of knowing when the submodules are out of sync with the main repo. Plus, you can still change your working directory to the submodule itself and use git status within it as per usual to see more information. See this question for more details about what "dirty" means.
