Like, say, constructing Well, even when the program is spending more time in other tasks, why use a slow class when you can easily replace it with a faster one that does the same thing? And about the synchronization: in many cases, when you need synchronization, you will need to synchronize something more than just the Collection manipulation. And if the Collection handling is already within a synchronized block, why use one more synchronization block inside another one? -- Jukka Lahtinen
