Well, ACK filtering/thinning is a simple trade-off: redundancy versus bandwidth. Since the RFCs say a receiver should acknoledge every second full MSS I think the decision whether to filter or not should be kept to
Why does it say to do this? What benefit is there to either end system to send 35kPPS of ACKs in order to facilitate a 100 megabyte/s of TCP transfer?
Sounds like a lot of useless interrupts and handling by the stack, apart from offloading it to the NIC to do a lot of handling of these mostly useless packets so the CPU doesn't have to do it.
Why isn't 1kPPS of ACKs sufficient for most usecases? -- Mikael Abrahamsson email: swm...@swm.pp.se _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
