Self cost 0.03 vs 0.02. I think the difference will not be large because 
the difference in handling is very little.

If the autoloader is used, than files are included only once.

Should not be relevant for TYPO3 class files.

Cannot tell about extensions and I am 99.99% sure that core uses only 
require_once.

This should depends on the system factors + PHP parsing speed. The larger 
the file, the slower the speed. But one large file would be faster than 10 
smaller files that are of the same size together.

Varies greatly.
