A benchmark is test that measures the performance of a system or subsystem on a well-defined task or set of tasks. Benchmarks are often used to measure general things like graphics, I/O, computing (integer and floating point), etc., performance, but most measure more specific tasks like rendering polygons, reading and writing files, or performing operations on matrixes.

CPU Benchmarks
The following results were obtained using nbench 2.2.2
All nbench results are in comparison to an AMD K6 233Mhz reference system.

Bonnie++ I/O Speeds for Encrypted Drive on HG
Here is a speed comparision using Bonnie++[5] as a diagnostic tool. Fifilein is trying to use AES/DMCrypt and his numbers are in the speed comparision too[6] all numbers are from an HD-HGLAN (HG).
