US Patent 10275239 Deriving application-specific operating parameters for backwards compatiblity

Performance of a legacy application may be characterized for subsequent adjustment of operating parameters when running the legacy application on a new system. Performance information for the legacy application is recorded or derived while running the legacy application on the legacy system. One or more performance characteristics for the legacy application running on the legacy system are determined by analyzing the performance information, the one or more performance characteristics including one or more key performance metrics and other performance information. The one or more key performance metrics must be met when the legacy application is run on the new system. The other performance information is useful for later adjustment of operating parameters of the new system when running the legacy application on the new system.
