Introduction and downloadable LSPR

The purpose of the LSPR is to provide reliable relative capacity data for System/370, System/390 and z/Architecture processors. The LSPR provides sets of workload sensitive ITRR tables and a methodology for their proper use in-order to reliably determine relative processor capacity for production workloads. The accompanying tables describe LSPR performance data as of the indicated date. For a description of the LSPR data, the guidelines or methodology for its use, and other details, please consult the latest Large Systems Performance Reference document that is available in PDF format via the web link. This version is only available in PDF format and can be downloaded with your browser.

In order to use the PDF file you must have Acrobat Reader installed. (Acrobat Reader 7 is recommended).
