Performance considerations
Chapter 15.
In this chapter we emphasize the importance of a complete tuning methodology.
We hope you will gain an understanding of all the related components and
understand the importance of making changes one at a time, then retesting
against a base-line performance number.
Misinterpreting the results of performance-related testing is also common.
Careful
concise
Ensure that you follow a logical and documented process.
and
are two important words when describing a tuning exercise.
We discuss parameters that can be tuned to get the maximum performance
during backup, archive, restore, and retrieve operations. Remember that an IBM
Tivoli Storage Manager implementation is typically quite complex, covering a
range of variables that could affect performance.
You will find much more detailed information about performance tuning and the
available parameters in IBM Tivoli Storage Manager Performance Tuning Guide,
SC32-9101.
