Xbench was developed by Spiny Software to provide a comprehensive benchmarking solution for Mac OS X. Xbench is useful not only for comparing the relative speeds of two different Macintoshes, but also for optimizing performance on a single machine. Xbench is accompanied by a website that allows graphical side-by-side comparison of any out of thousands of submitted benchmarks.
