In multi-user mode, run untimed benchmarks as often as necessary, capturing response time and throughput metrics. Resolve:
Differences, such as cache hit rate, to the pre-upgrade state
Bottlenecks
Other problems or mistakes
Be sure that you have enough default data cache after the upgrade. Tune as needed to fix problems. Between runs, restore your databases from backup or perform a quick reset.
Refer to the Performance and Tuning Guide for more information. See also Technical Information Library for the latest TechNotes and White papers on issues that may affect performance.
