Criterium (the benchmarking library used here) uses multiple runs to obtain tighter bounds on amortized performance, as well as techniques to account for the effects of garbage collection and JIT compilation. See https://github.com/hugoduncan/criterium https://github.com/hugoduncan/criterium for a brief overview, as well as links to the pitfalls and statistical techniques involved in JVM benchmarking.
