Performance

“The degree to which a system or component accomplishes its designated functions within given constraints, such as speed, accuracy, or memory usage.” [IEEE Std. 610.12]

Performance testing which can apply to networks, websites and web-based applications involves load testing and benchmarking.

What is load testing?

• Load testing is employed to determine if your system (application) and servers (website) are equipped to handle the network traffic anticipated at deployment, as well as increased network traffic in the future.

What is Benchmarking?

• A benchmark is a standard of excellence or achievement used to compare and measure similar products.

• Benchmarks are designed to mimic a particular type of workload on a component or system.

• What PC components could you measure?

Other Considerations

Dependability• "The degree to which a system or

component is operational and accessible when required for use.”

[IEEE Std. 610.12]

Other Considerations

Modifiability• “(1) The ease with which a software

system or component can be modified to correct faults, improve performance or other attributes, or adapt to a changed environment.

[IEEE Std. 610.12]

Other Considerations

Usability“The ease with which a user can learn to

operate, prepare inputs for, and interpret outputs of a system or component.”

[IEEE Std. 610.12]

Other Considerations

• Security“Secure systems are those that can be

trusted to keep secrets and safeguard privacy.”

[J. Rushby, Critical System Properties: Survey and Taxonomy, SRI International, Technical Report CSL-93-01, May 1993]

Other Considerations

• SafetySafety is that property of a computer system such that reliance can justifiably be placed in the absence of accidents.
