Title: Indirect software performance analysis

Abstract: Performance impact of a computing system component on a transient end-to-end system operation is estimated by profiling an overall characteristic for a transient end-to-end system operation, and simultaneously profiling a program code component for a second characteristic, thereby collecting a first pair of data points, repeating the operational period while introducing a known artificial delay into the program code component, and while profiling the overall performance characteristic for the system and for the program code component, thereby collecting pairs of data points for each repetition of the operational period for each of the artificial delays; curve fitting and analyzing intercepts of the collected data points to estimate the effect of the artificial delays in the program code component on the transient end-to-end system operation; and reporting the estimate correlated to potential optimal transient end-to-end system operation.
