An improvement in a networked digital computing system comprises an Information Resource Manager (IRM) operable to communicate with elements of the digital computing system to obtain performance information regarding operation of and resources available in the computing system, and to utilize this information to enable the IRM to adjust the application parameters relating to application execution, thereby to optimize execution of the at least one application program. The IRM comprises (1) a performance profiling system operable to communicate with the at least one CPU, network and SAN and to obtain therefrom performance information and configuration information, (2) an analytical performance model system, operable to communicate with the performance profiling system and to receive the performance information and configuration information and to utilize the performance information and configuration information to generate an analytical model output, the analytical model output comprising any of performance statistics and updated application parameters, and (3) an application parameter determination system, operable to communicate with the analytical model system, to receive therefrom the analytical model output, to determine, in response to the analytical model output, updated application parameter values, and to transmit the updated application parameter values to at least one application running on the digital computing system, for use by the application to set its application parameters, thereby to optimize execution of multiple applications running on the digital computing system, using updated runtime parameters.
