IBM iSeries benchmarks

IBM has developed benchmarks to compare the performance of their various iSeries server offerings. Computational Intensive Workload (CIW) measures performance in a situation where there is a high ratio of computation to Input/Output communication. The reverse situation is simulated by the Commercial Processing Workload (CPW).[1]

The CPW is a simplified variant of the industry-wide TPC-C benchmarking standard.[2]
