Abstract
Technologies for estimating deviations in the performance characteristics of a newer version of software relative to an older version. Such performance characteristics include cache misses, pages faults, and the like. Estimations are typically made by instrumenting and profiling an older version binary, determining differences in code blocks between the older and a newer version, propagating profile data from the older version to the newer version based on a simulation heuristic, and estimating performance deviations based on the older version, the profile data, configuration parameters, and the changes in the newer version without actually executing the newer version of the binary.
