- pitaj 6y agoI assume bufferbloat will affect your latency, right? Is there really a tradeoff between latency and throughput?
- amarshall 6y agoThe negative effect of bufferbloat is indeed increased latency. But bufferbloat is a specific scenario—latency may be low when throughput is low even if the network path is susceptible to bufferbloat.
- nullc 6y ago> Is there really a tradeoff between latency and throughput? Assuming that the path under test latency is small to begin with, increasing buffering from reasonable to large to absurd generally provides a tiny and rapidly diminishing throughput increase. Part of the reason bufferbloat exists is because of norms in equipment testing focusing on throughput (esp for single/few tcp streams) and drops while ignoring other effects.
- colordrops 6y agoYou can measure bufferbloat and adjust appropriately if your router supports it.
