Technologies for performance monitoring and management with empty polling

A computing device to monitor performance comprising:

• polling training circuitry to (i) perform an empty polling training workload by a processor core of the computing device, the empty polling training workload based on an empty input queue and (ii) determine one or more empty polling thresholds in response to performing the empty polling training workload, respective empty polling thresholds indicative of a number of empty polls per sampling interval;
• packet processing circuitry to perform a packet processing workload on network traffic with the processor core of the computing device;
• and
• power configuration managing circuitry to:
• compare a first number of empty polls by the packet processing workload to the one or more empty polling thresholds in response to performance of the packet processing workload, the comparison to determine whether the first number of empty polls is less than one of the one or more empty polling thresholds;
• and
• cause a power adjustment of the processor core in response to the comparison of the first number of empty polls to the one or more empty polling thresholds, the power adjustment to increase a performance level of the processor core in response to a determination that the first number of empty polls is greater than one of the one or more empty polling thresholds.

A method for performance monitoring, the method comprising:

• performing, by a computing device, an empty polling training workload by a first one of one or more processor cores of the computing device, the empty polling training workload based on an empty input queue;
• determining, by the computing device, one or more empty polling thresholds in response to performing the empty polling training workload, wherein respective ones of the empty polling threshold are indicative of a number of empty polls per sampling interval;
• performing, by the computing device, a packet processing workload on network traffic by second ones of the one or more processor cores of the computing device in response to determining the one or more empty polling thresholds;
• comparing, by the computing device, a first number of empty polls by the packet processing workload to the one or more empty polling thresholds in response to performing the packet processing workload, the comparison determining whether the first number of empty polls is less than one of the one or more empty polling thresholds;
• and
• configuring, by the computing device, power management of the second ones of the one or more processor cores in response to comparing the first number of empty polls to the one or more empty polling thresholds, the performance level of the second ones of the one or more processor cores increased in response to determining that the first number of empty polls is greater than one of the one or more empty polling thresholds.
