Introduction

Perfidix is a tool for developers to conveniently and consistently benchmark Java code. It can quickly answer which implementation is faster. Without the need to launch a full-fledged profiling application or rewrite the same Java code to measure the execution time again and again.

Eventhough Perfidix is simple to use, it still provides a sound statistical output for taking a decision.

JUnit like handling.

Perfidix is intentionally designed to be used like JUnit 4.x, i.e., it provides annotations to discover which methods should be benchmarked how many times. The eclipse plugin or custom code allows to run a package, class, or method as a Perfidix benchmark and to collect the execution time statistics for each method in the console as text or CVS output.

The output includes package, class, and method name together with the number of runs, min, max, average, standard deviation, and confidence intervals. The number of runs can individually be specified per package, class, or method. Besides this, the number of runs can be chosen by a probability distribution function to simulate typical workloads.

Do a quick benchmark, analyze later.

Perfidix was created at the University of Konstanz at the Distributed System Group.

It greatly assisted the research by allowing for quick benchmarking of different algorithms and data structures. Furthermore, all benchmark results could easily be made persistent for later analysis and compilation into charts.
