I already check for the string length in order to reduce the comparisions. I didn't post the code due to make it as short as possible.

I'm currently testing the Text::LevenshteinXS method. It is extremly fast in comparision with the String::Similarity, but I still have to make some changes in order to get the same results.

UPDATE

I've made a mistake testing the Text::LevenshteinXSL. Here I post the real time each method took using a 5000 string collection

 
Text::LevenshteinXS -> 2m 40s
String::Similarity -> 3m
