GitHub Actions Test Results Accuracy Issue about mathtools HOT 2 CLOSED

Unless there is another method besides measureNanoTime that can record time measurements to nanosecond accuracy, the only option remaining is to perform each operation 100x.

One issue with this approach is that the operation itself is not isolated, the cache must be cleared between each operation which may affect the result. To work around this, the Cache can be instantiated 100x, and each cache can be accessed in sequence during the measurement. This would isolate the operation, and enable the cache clearing to be performed post-measurement.
