rPerf (Relative Performance)
Also known as: Relative Performance
An IBM benchmark metric used to compare relative processing capacity across Power Systems for AIX and Linux workloads.
Relative Performance (rPerf) is IBM's benchmark metric for comparing processor capacity across Power Systems generations and models for AIX and Linux workloads, playing a role similar to CPW for IBM i. rPerf figures are commonly referenced during Power11 sizing conversations when moving AIX or Linux workloads from an older Power generation.
