Measuring performance using the PerfMeasurement.jsm code module

for instance, let's measure instructions executed, cache references, and cache misses: let monitor = new perfmeasurement(perfmeasurement.cpu_cycles | perfmeasurement.cache_references | perfmeasurement.cache_misses); this creates a new perfmeasurement object, configured to record the specified event types.
...now we want to benchmark a function that is pretty fast (but not fast enough), so we run it several thousand times: for (let i = 0; i < 10000; i++) { set_up_some_state(); monitor.start(); code_to_be_benchmarked(); monitor.stop(); clean_up_afterward(); } we call the perfmeasurement object's start() method when we want to start recording, and stop() when we want to stop recording.
