IBM’s Relative Performance (rPerf) metric is a great tool for comparing commercial workload performance between different Power System servers. It’s often. This post outlines a recent Nigel Griffiths tweet about estimating rperf for your LPAR. Read on to find out more. Articles on IBM AIX performance including server throughput, system performance and IBM AIX commands.

There is no way to convert a roltp number to a rPerf. We’ll focus on the rPerf benchmark, which is an estimate of commercial processing performance, relative to other pSeries systems, used by IBM. The model simulates some of the system operations, such as CPU, cache and memory. Specifically, a computer benchmark is a computer program that performs a strictly defined workload set of operations and returns some form of measurable result i.
If you want to know what rperf used to work out your rating use: How do I use the vio If capped should the script use Entitlement and rpert VP?

Latest AIX with Service Packs – like all benchmarks, the best operating system version is used to get those latest performance fixes and improvements.
The script will give a lower than actual rPerf number. Some of the more notable benchmark suites are Standard Performance Evaluation Corp.

This is normal tuning like disk queue depth, memory use, large network packets. Implement these techniques to improve data-center resiliency. I call these my Ten Golden Rules or considerations to remember while using rPerfs for sizing. The rperf numbers are only available for certain number of CPUs. If it says estimated then it is NOT an official number. Second, rPerf numbers are expressed in terms of throughput as opposed to speed.
There are many pitfalls in using benchmarks in computer sizing endeavors.

Bug Free – users have to be willing to upgrade firmware, AIX and application software, as necessary. Note, although rPerf may be used to compare estimated IBM UNIX dperf processing performance, actual system performance may vary and is dependent upon many factors, including system hardware configuration, software design, and configuration.
