Abstract: Tracking resource use includes determining when the resource is allocated, determining when the resource is first used, determining when the resource is last used, and determining when the resource is deallocated. The resource may be a software object. Deallocating the resource may be performed automatically by a run time system when there are no remaining references to the object in run time code or variables. Deallocating the resource may include at least one of: setting a flag for the resource and adding an identifier for the resource to a list of resources to be deallocated. Time measurements may correspond to a count of garbage collection cycles. Tracking resource use may also include determining additional resource usage metrics.

Abstract: Computation of a metric, termed “memory pressure,” provides an indication of software application scalability, in terms of memory, when making changes to multi-user applications. The memory pressure metric may be measured on a single user application run and does not require running the application under load tests. Since the metric can be measured on single user application runs, software testing and assessment takes considerably less time, resulting in developer productivity increase.
