I'm wondering how you're measuring check points? Btrfs does a transaction commit ever 30 seconds, so finding 7 commits per second seems strange. We do have a lighter weight commit that is done for fsyncs, but this is not a full check point. There's no garbage removal in btrfs, we use reference counting instead of a traditional log structured design. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
