File::Slurp says in its description: Efficient Reading / Writing of Complete Files

Well, that affirmation could be just some propaganda from the module author.

Anyway, writing lots of very small files, you are benchmarking an extreme, non representative, case. Looking at the module source code it seems that it introduces some overhead in order to support all its features, but that overhead would probably become insignificant when your files reach a more usual length.
