Computer Systems can be set with a myriad of options, determining an optimal set-up for any particular application can be difficult. This pilot study demonstrates how numerous I/O performance tests with varied hardware and software configurations can be efficiently compared to determine an optimal set-up for an application. To simplify this process a statistic was developed to provide a quick relative performance comparison. This metric can be arithmetically manipulated to provide meaningful averaging of multiple performance tests into a single overall performance indicator. We will illustrate how RIP is used by comparing I/O performance test results on approximately 50-100 different hardware/software set-ups; RIP results will be compared to results from a random forest repeat sampling technique to determine the most influential performance factors.
