The fastest is using a hash. For very structured data you might in a few cases find slightly faster methods, but really, nothing normally beats hashes in this discipline.

But please be more specific: You talk about string lengths, but you show us arrays. Strings are not arrays outside of the C language. And qw() does produce arrays, not strings.
