class ResponsivenessMetric(telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric)
`` | `Computes metrics that measure respsonsiveness on the record ranges. total_big_jank_thread_time is the total thread duration of all top slices whose thread time ranges overlapped with any thread time ranges of the records and the overlapped thread duration is greater than or equal
USER_PERCEIVABLE_DELAY_THRESHOLD_MS.
biggest_jank_thread_time is the biggest thread duration of all
top slices whose thread time ranges overlapped with any of records' thread
time ranges.
All *_time values are measured in milliseconds.
