Score overall when using the XBench test - higher scores (longer bars) are better. Xbench was developed to provide a comprehensive benchmarking solution for Mac OS X. Xbench is useful not only for comparing the relative speed 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 comparisons of any out of the tens of thousands of submitted benchmarks. Note: Frequently I receive emails from readers complaining that Xbench is not accurate time and time again when tested on the same machine. To be very fair in these tests, Xbench is the first application I test with on any machine, and my testing procedures are very consistent. I allow the machine to fully boot, and the processor usage graph must remain at 0 for 10 seconds before I start this test. Upon bootup, Mac OS X performs a number of housecleaning tasks and you will see that even though you can click and launch applications, the system is truly not idle immediately and it's safer to wait until it finished these processes before continuing. Another Note: The G5 systems were set to maximum performance in the energy saver preference pane, and disabled the bus slewing ability to allow these tests to be run at full speed. If you don't do that, the G5s scores are substantially less.
