<i>maximum resolution of sampling is higher, since it has lower overhead</i><p>The article claims otherwise.<p>This is apparently mostly related to the costs of preemption and resulting icache replacement.<p><i>though it could not be said with certainty it was the same invocation, it would be enough to see that a majority of time blocked was elapsed there</i><p>But that&#x27;s not quite what&#x27;s being discussed. The main interesting thing here is tracking what oddness causes outlier worst-case times, which very much does require tracking individual invocations.
