[!NOTE] #### Should I set up on-demand loading?
You probably don't need to.
A properly implemented Vim plugin should already load lazily without any help
from a plugin manager (`:helpautoload`). So there are few cases where these
options actually make much sense. Making a plugin load faster is the
responsibility of the plugin developer, not the user. If you find a plugin
that takes too long to load, consider opening an issue on the plugin's issue
tracker.
Let me give you a perspective. The time it takes to load a plugin is usually
less than 2 or 3ms on modern computers. So unless you use a very large number
of plugins, you are unlikely to save more than 50ms. If you have spent an hour
carefully setting up the options to shave off 50ms, you will have to start Vim
72,000 times just to break even. You should ask yourself if that's a good
investment of your time.
Make sure that you're tackling the right problem by breaking down the startup
time of Vim using `--startuptime`.

On-demand loading should only be used as a last resort. It is basically a
hacky workaround and is not always guaranteed to work.
