Performance test of software products with reduced duration

A computer program product, comprising one or more computer readable hardware storage devices having computer readable program code stored therein, said program code containing instructions executable by one or more processors of a computer system to implement a method for testing performance of a software product, said method comprising:

• performing, by the one or more processors, one or more complete executions of a performance test of corresponding versions of the software product, said complete executions of the performance test identifying a steady state value of each performance parameter of at least one performance parameter monitored during the performance test after each performance parameter has transitioned to a steady state during the performance test,
• determining, by the one or more processors, a performance profile of the software product according to the complete executions of the performance test, said performance profile modeling a complete trend of the at least one performance parameter during the complete executions of the performance test,
• performing, by the one or more processors, one or more partial executions of the performance test of corresponding further versions of the software product, each partial execution of the performance test having a partial duration preceding the steady state of each performance parameter, and
• estimating, by the one or more processors, corresponding results of the partial executions of the performance test according to the performance profile from corresponding partial trends of the at least one performance parameter during the partial executions of the performance test.

A computer system, comprising one or more processors, one or more memories, and one or more computer readable hardware storage devices, said one or more hardware storage device containing program code executable by the one or more processors via the one or more memories to implement a method for testing performance of a software product, said method comprising:

• performing, by the one or more processors, one or more complete executions of a performance test of corresponding versions of the software product, said complete executions of the performance test identifying a steady state value of each performance parameter of at least one performance parameter monitored during the performance test after each performance parameter has transitioned to a steady state during the performance test,
