The short answer is answer is "kind of" My understanding is that Nagle will delay segments until they're either MSS-sized or until segments "down the pipe" are acknowledged. As RDB isn't able to bundle if the payload is more than MSS/2, only an application that that sends data less frequent than an RTT would still theoretically benefit from RDB even if Nagle is on. However, in my opinion this is a scenario where Nagle itself is void: If you transmit more rarely than the RTT, enabling Nagle makes no difference. If you transfer more frequent than the RTT, enabling Nagle makes RDB void. -Jonas -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
