Hello! I need to switch from htb2 to htb3, because of speed issues (for me, htb2 is unable to handle more then 100mbit duplex with ~550 classes), kernel profiling shows htb_dequeue_prio at 1st place with 3x isolation. So, I''ve moved from 2.4.19 to 2.4.25 kernel (hi-pac for classification/marking and htb3 for queueing), and traffic rate drop from 100 to 20mbit. What can be wrong? The only change I see is htb2 -> htb3 Here is my qdiscs/classes/filters example qdisc htb 1: dev eth0 r2q 10 default 2500 direct_packets_stat 4604 ver 3.13 qdisc sfq 100: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec qdisc sfq 3300: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec qdisc sfq 3301: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec qdisc sfq 3302: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec qdisc sfq 3304: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec qdisc sfq 3305: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec qdisc sfq 3306: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec qdisc sfq 3308: dev eth0 quantum 1514b limit 128p flows 128/1024 perturb 5sec [skip] class htb 1:1 root rate 200Mbit ceil 200Mbit burst 263690b/8 mpu 0b cburst 263690b/8 mpu 0b level 7 class htb 1:2 root rate 200Mbit ceil 200Mbit burst 263690b/8 mpu 0b cburst 263690b/8 mpu 0b level 7 class htb 1:3300 parent 1:1 leaf 3300: prio 0 quantum 13107 rate 1Mbit ceil 1126Kbit burst 1023b/8 mpu 0b cburst 0b/8 mpu 0b level 0 class htb 1:3301 parent 1:1 leaf 3301: prio 0 quantum 10240 rate 800Kbit ceil 1Mbit burst 1023b/8 mpu 0b cburst 0b/8 mpu 0b level 0 class htb 1:3302 parent 1:1 leaf 3302: prio 0 quantum 13107 rate 1Mbit ceil 1200Kbit burst 2Kb/8 mpu 0b cburst 0b/8 mpu 0b level 0 class htb 1:3304 parent 1:1 leaf 3304: prio 0 quantum 4915 rate 384Kbit ceil 384Kbit burst 2Kb/8 mpu 0b cburst 0b/8 mpu 0b level 0 [skip] filter parent 1: protocol ip pref 50 fw filter parent 1: protocol ip pref 50 fw handle 0x14b4 classid 1:5300 filter parent 1: protocol ip pref 50 fw handle 0x14b5 classid 1:5301 filter parent 1: protocol ip pref 50 fw handle 0x14b6 classid 1:5302 filter parent 1: protocol ip pref 50 fw handle 0x14b8 classid 1:5304 filter parent 1: protocol ip pref 50 fw handle 0x14b9 classid 1:5305 filter parent 1: protocol ip pref 50 fw handle 0x14ba classid 1:5306 [skip] -- Michael Vasilenko _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Both HTB algorithms are very different so that one can expect different behavior with different data/rules. But I can admit that this 5x drop is rather big and unfortunate. devik _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

Look for classes with small (or negative) tokens or ctokens - these are in throttling state and are slowing throughtput - then think if it is ok .. From data you send one can''t decide what''s bad. In any case and as I said before, behavioue changed a bit so that results can be a bit different a may need tc script changes. devik _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/

I see you have cburst 0 ! It is not allowed
and is described in docs. What was commands to
create the classes ?

Probably it will settle down after some while. I suspect there is problem in your way of measuring the rate. Also you can deliberately increase (c)burst to more than default, say to 20kB - the larger the burst it the more insensitive to CPU load it is ... devik _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
