1. A system that facilitates determining when to invoke a physical design tool, comprising: memory; one or more processors coupled to the memory; a database management system, stored in the memory and operable on the one or more processors, that captures workload information of at least one existing configuration; a notification component that: receives the captured workload information, determines, based upon a pre-determined improvement threshold, that a comprehensive tuning session would produce a better configuration than the at least one existing configuration, and invokes the physical design tool in response to the determination by the notification component that the comprehensive tuning session would produce the better configuration than the at least one existing configuration, the notification component configured to: calculate at least a lower bound improvement that mitigates false positives, and generate a valid configuration illustrating the calculated lower bound improvement.
