[erlang-questions] Anonymous functions and performance

[Robert Virding]

Also making just one call in the test is so fast that the timing will be dominated by setting up the test and what is done inside the fun. In your case you should call the funs "many" times with a really trivial list. I would not expect there to be much different but I haven't measured.
