The optimum buffer state for throughput is 1-2 packets worth - in other words, if we have an MTU of 1500, 1500 - 3000 bytes. Only the bottleneck
No, the optimal state for througbut is to have huge buffers and have them filled. The optimal state for interactivity is to have very small buffers. FQ_CODEL tries to strike a balance between the two at 10ms of buffer. PIE does the same around 20ms. In order for PIE to work properly I'd say you need 50ms of buffering as a minimum, otherwise you're going to get 100% tail drop and multiple sequential drops occasionally (which might be desireable to keep interactivity good).
My comment about 50ms is that you seldom need a lot more. -- Mikael Abrahamsson email: [email protected] _______________________________________________ Cerowrt-devel mailing list [email protected] https://lists.bufferbloat.net/listinfo/cerowrt-devel
