The default now is 250 and with 19k burst that fits the speed you get really well - with 512 it would be around 70meg. I would get rid of the 2 burst settings you use. >> Not sure can you show output of tc -s -d class ls dev eth0 while it's >> running at 2x speed. > > > class htb 1:1 root rate 100Mbit ceil 100Mbit burst 24Kb/8 mpu 0b cburst > 132644b/8 mpu 0b level 7 > Sent 741267447736 bytes 735629628 pkts (dropped 0, overlimits 0) > rate 4316188bps 22688pps > lended: 489885589 borrowed: 0 giants: 0 > tokens: -78 ctokens: 6677 > > class htb 1:10 parent 1:1 leaf 10: prio 0 quantum 200000 rate 50Mbit > ceil 80Mbit burst 19Kb/8 mpu 0b cburst 106440b/8 mpu 0b level 0 > Sent 740240463634 bytes 734522966 pkts (dropped 429910165, overlimits 0) > rate 4233957bps 22358pps > lended: 244988819 borrowed: 489885528 giants: 0 > tokens: -293 ctokens: 6636 > > class htb 1:20 parent 1:1 leaf 20: prio 0 quantum 13107 rate 1Mbit ceil > 1Mbit burst 2Kb/8 mpu 0b cburst 2Kb/8 mpu 0b level 0 > Sent 755354078 bytes 755048 pkts (dropped 0, overlimits 0) > rate 84198bps 321pps backlog 4p > lended: 755220 borrowed: 61 giants: 0 > tokens: -21517 ctokens: -21517 84198 bps - tc means bytes/sec by this, so it's < 1mbit. Htb uses really long (100 sec) average for its rate so it probably is giving 1mbit.
