Performance Audit Litany 2007
Here is the updated 2007 version of questions from the Computer Measurement Group (CMG) award winning Performance Audit Litany (PAL) paper. PAL provides a framework for beginning any performance study. The Performance Audit Litany 2007 starts with a blank slate and gathers its strength as it fills in answers to questions that form the foundation of the problem at hand. PAL is, in other words, the proverbial “good beginning.”
— Dutch proverb
It should only take you a few minutes to use this list of questions to launch your performance troubleshooting efforts on the right foot. When combined with T4 & Friends data showing the key system, network, storage, and business factors from the systems in question, you will find yourself in an excellent position to determine and then fix the cause of the slowdown.
Please note that it is perfectly OK if you don’t know the answer to a given question. Just jot down: “Don’t Know” or draw a dashed line. Surprisingly, you will find that the questions that cannot be answered right away often provide the most important clues as to what to do next.
If you would like some assistance in interpreting the answers you get or in how best to use the PAL answers in conjunction with T4, please contact us.
If you have access to T4 & Friends data, you will find it particularly helpful in answering many of these questions in more detail. The PAL answers will help point you to the most useful periods of time and the T4 data will make it easier for you to see what processes were at work during those periods.
