- supporting systems software
- accidental systems software
- replacement systems software
- intentional systems software

How to Avoid Erroneous Results in Performance Testing [29884]
Some Rules of Thumb from the School of Hard Knocks
There are several rules of thumb for predicting the I/O behavior of a system that Matt Hayward has derived from his labors in the vineyard of performance testing. They are:

- When simulating, be sure to simulate the actual application workload
- Evaluate latencies using histograms, not averages
- Verify your performance tests give reproducible results
- Run tests in the same time frame as the production application, and for similar durations
- Ensure the test data is similar to what the application will use and produce
Ignore these rules at your peril, he cautions.
