No, it shows that benchmarking is a bad idea if one doesn't know what's 
being measured.
I suspect that garbage collection has disturbed your results. The 
effects are  particularly visible because Erlang uses a stop-the-world 
collector (though it should be more appropriately named 
"stop-the-process collector" in an Erlang context).
