Abstract
A polling interval of a poller in a data storage system is dynamically adjusted to balance latency and resource utilization. Performance metrics are regularly estimated or measured and derived values are calculated including a latency share and a cost per event, based on a latency metric for polling latency and a cost metric for use of processing resources. A target latency share is adjusted by (1) an increase based on a CPU utilization metric being above a utilization threshold, and (2) a reduction based on the CPU utilization metric being below the utilization threshold and the cost per event being lower than a cost-per-event threshold. The polling interval is adjusted by (1) increasing the polling interval based on the latency share being less than the target latency share, and (2) decreasing the polling interval based on the latency share being greater than the target latency share.
