I disagree with it not making sense, if there are less objects in
memory when you are trying to initialize the next required object the
engine will be able to find it quicker. Seems to be the case at least.
These results were ran multiple times and got the same numbers. The
only files required were those that were going to be needed for it to
run the script.

That doesn't even make common sense, autoload will never be faster
then straight require if the exact same number of files are called
each time, there is less overhead.
The only way for them to get the below results would of been to
include every file in propel straight out even if it wasn't used which
is just stupid.
File per file autoload is slower, If you know a file is going to be
needed without question you will get better performance if you require
it.
The best solution is to find a middle ground, what files get called
50%+ of the time in your application and preload those, let the rest
be autoloaded.
This would give you the best of both worlds, performance and flexability.
