Benchmarks

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