Abstract: Techniques are disclosed involving techniques that may dynamically adjust processor (e.g., CPU) performance. For instance, an apparatus includes a counter, an efficiency determination module, and a management module. The counter determines a number of event occurrences, wherein each of the event occurrences involves a processor component (e.g., a processor core) awaiting a response from a device. The efficiency determination module determines an efficiency metric based on the number of event occurrences. The management module establishes one or more operational characteristics for the processor component that correspond to the efficiency metric. Other embodiments are described and claimed.
