Why should rPerf be used instead of RPE2?
Asked by: Enkmin
A customer has DB2 running on three POWER5 520s with AIX 5.2 and is planning to consolidate the systems on a new Power 740 with AIX 7.1. The customer is reviewing the RPE2 benchmark data to validate that the proposed solution will work. Why should rPerf be used instead of RPE2?
The rPerf benchmark is run on every server model to obtain performance data, while RPE2 frequently uses extrapolations.
rPerf includes the performance impact to AIX due to the introduction of new features, while
RPE2 does not focus on software versions
The rPerf metric considers the number of cores, memory utilization by the applications, I/O
transactions, and RPE2 only measures core performance.
rPerf is obtained by duplicating the production environment, representing the most accurate performance of the installed systems, and RPE2 uses analytical models.
