Steps to investigate CPU performance on release migration
This best practice discusses methodologies and techniques to investigate a CPU performance regression across a release migration. When a regression occurs you need to be able to quantify it as well as try to determine the cause. You need to normalize results in a real world environment to compare results between DB2 releases. This web lecture shows you what to look for and how to go about the comparison. Specifics are given on how to use statistics and accounting trace workload indicators.
