Problem is some hardware cannot do this in a smart way, without paying the price of a sometime expensive copy. Thats why I refined this idea to actually trigger only if current memory needs are above a threshold. If packets are received and immediately consumed, without potentially staying a long time in a queue, it doesnt really matter they use 200 or 400% more ram than the rightly sized packets. _______________________________________________ Codel mailing list [email protected] https://lists.bufferbloat.net/listinfo/codel
