@cphoward cphoward commented Oct 16, 2023

This change seeks to expose libuv's internal uv_metrics_idle_time to permit users to tune their applications. This change is inspired by Nodejs' internalEventLoopUtilization.

The heart of this change is:

def _event_loop_utilization(self):
 """Returns idle and active time in milliseconds and the percentage of
 time the event loop is active
 """
 ...
 return idle, active, utilization
