Здрасти,
Пробва ли да ползваш за leaf дисциплина sfq вместо pfifo?
tc qdisc add dev eth1 parent 1:10 handle 10: sfq perturb 20
При мен htb/sfq йерархия с над 2к класа, през която минават
към 6Мбит/с почти постоянно се справя прекрасно. SFQ ще се погрижи
всички конекции под даден HTB клас да получат равен дял от
bandwidth-a.
Дано помогне ;)
П.П. Друго предположение - дали hyperthreading-а на p4 не ти обърква нещата?
