With current concurrent collectors, the stop-the-world pauses are so short that they approach the pause times processes encounter for other reasons on untuned systems. But I meant something else: it's not always clear whether low-pause collectors are a win. A totally made-up example: Is it worthwhile to add 2ms processing time to every request to avoid that every 7 to 10 minutes, there is a 20% chance that there is a garbage collection that delays all requests currently in flight by 40ms?
