Spanish from Spain has an official dictionary that dictates what is correct and isn’t. You can’t be more prescriptive than that. Sure, that dictionary adds words based on usage, even ones that are clear misspellings of the “real” word, but they are marked as so.

5 seconds at every boot and shutdown is important.

The reason you shouldn’t blindly benchmark an init system is because most of the time is not caused by the init system itself being slow, but the processes it manages being slow.

As the other commenter says, it is very easy to make the system “faster” by just configuring the timeouts to be lower. If you just set the timeout to 0 it will be very fast, but it won’t be a very good system.
