Dhrystone is a standardized speed test with a specific workload mix.Different CPU architectures have different strengths and weaknesses. For example, a 75 MHz SPARC easily beats a 400 MHz PentiumII at AES, but loses in zlib decompression, so there is no way to tell which one is faster.The Whetstone and Dhrystone tests are both synthetic tests that are useful mostly as a benchmark for scientific computing because of their composition, but there is no consensus on anything that is closer to a "realistic" workload, especially as realistic workloads for embedded devices will consist of a lot of idle time.The result from a Dhrystone test is expressed in a unit of calculations per second, which does not necessarily correspond to actual CPU instructions per second, but is a tiny bit more comparable.
