AIX RPERF PDF

How do these performance attributes translate into tangible business benefits? While the document is tailored to IBM i clients, much of the introductory material in the performance section is OS-agnostic. While response time and throughput are generally related—increasing throughput normally leads to a decrease in response time—a system can throw a lot of resource at some amount of processing, causing a decrease in response time at the expense of throughput to other processing. The IBM Power Systems platform is built with a balanced system design to maintain good throughput and responsiveness—that is, good performance.

None of the above, continue with my search. This script does that. The official rPerf numbers are only available for certain numbers of CPUs. If you want to know what rperf used to work out your rating use: rperf -v. Page Feedback. United States English English. IBM Support Check here to start a new keyword search. No results were found for your search query. If you want to know what rperf used to work out your rating use: rperf -v There are some example problems you may encounter: Older machines don't have rPerf numbers so the script outputs the roltp number.

There is no way to convert a roltp number to a rPerf. You will have to apply your own rules for that. In this case, the script guesses the rPerf based on rPerf numbers in a fairly crude way. These are a simple calculation and will not be exact - i. The script will give a lower than actual rPerf number. If capped should the script use Entitlement and not VP? How will the script get updated?

There is no simple way to convert from roltp to rPerf - sorry. If it says estimated then it is NOT an official number. For LPARs the number may be estimated but it is a simple maths calculation i.

Actual performance will vary based on application and configuration details. Although rPerf may be used to compare estimated IBM UNIX commercial processing performance, actual system performance may vary and is dependent upon many factors including system hardware configuration and software design and configuration. Variations in incremental system performance may be observed in commercial workloads due to changes in the underlying system architecture. Sometimes you may want to compare the rPerf of different IBM Power Systems, some of which you may not even have access to. If you're replacing a POWER6 system with POWER8, you'll need some way to compare these systems so, for instance, you'll have a better understanding of the number of cores you'll need to activate for new or existing workloads. As long as you know the model number, the total number of cores on the system and the CPU speed, you can obtain some valuable information.

The Generic Workload can be a very versatile workload. It provides a controlled manner in which the user is allowed to enter specific resource requirements for characterizing a workload. These parameters include such things as rPerf and CPW processing requirements of a workload, the amount of memory, the number of disk arms, the amount of disk storage needed by the workload. Back to top. The processor section refers to the resource requirements for the central processor.
