—In this paper we show how program code and performance models can be made to cooperate seamlessly to support continuous software performance testing throughout the development lifecycle. We achieve this by extending our existing VEX tool for executing programs in virtual time so that events that occur during normal execution and those that occur during the(More)
We present a new approach to software performance analysis that aims to extend conventional profiling with some of the predictive capabilities of a performance model. The idea is to execute programs in virtual time, which allows hypothetical time scaling of the constituent parts of an application to be explored in advance of any speculative redevelopment(More)
