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