interceptors/performance/performance_history library

Classes

PerformanceHistory
A rolling window of recent performance samples, so the Performance tab can show a trend instead of only an instantaneous snapshot — whether a dip is constant or only happens during a scroll, whether memory is flat or climbing, are both invisible in a single-number readout.
PerformanceSample
One FPS/memory reading, taken roughly once a second by PerformanceTab.
