entrySet() vs. keySet()

README.md

This Gist is to answer: http://stackoverflow.com/questions/12639259/findbugs-warning-inefficient-use-of-keyset-iterator-instead-of-entryset-iterato

Bottom line: yes, if you are iterating over the whole map use .entrySet() instead of .keySet().

Most relevant stats: for 100 entries in the Map:
