Test Cycle: Testing for Performance

Untimed Benchmarks

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 at

for more information. See also

Technical Information Library for the latest TechNotes and White papers on

issues that may affect performance.

Timed Benchmarks

Always restore your databases from backup so they are in a known state when

running timed benchmarks. Gather response time and throughput metrics.

Tune as necessary to achieve your performance criteria.

Run tests as often as necessary to fix problems and be able to reproduce the

final results.
