Hi, I''ve been using htb fine to separate outgoing SMTP traffic from HTTP traffic so sending big emails doesn''t affect browsing. As long as ceil == burst and the sum of all rates don''t exceed the root class'' rate all is fine but when I incorporate ceil I would expect (from lartc howto) that when other classes are idle the remaining bandwith would be assigned in order of prio (I believe, again from howto that 0 is highest) to other classes, which is not happening. In particular, sending big test emails (with everything else idle) shows that SMTP traffic never exceeds exactly 3kbps, even with ceil set at 9kbps. I measured the speed with iptraf. What am I doing wrong? List of my classes. If you need more info, please let me know! # tc class show dev eth2 class htb 1: root prio 0 rate 13312bit ceil 13312bit burst 1732b cburst 5Kb class htb 1:20 root prio 7 rate 12bit ceil 12bit burst 1599b cburst 1599b class htb 1:5 root prio 2 rate 13312bit ceil 13312bit burst 1732b cburst 1732b class htb 1:6 root prio 3 rate 13312bit ceil 13312bit burst 1732b cburst 1732b class htb 1:7 root prio 4 rate 4096bit ceil 4096bit burst 1639b cburst 5Kb class htb 1:8 root prio 5 rate 3072bit ceil 9216bit burst 1629b cburst 1691b class htb 1:9 root prio 6 rate 3072bit ceil 9216bit burst 1629b cburst 1691b root class: 1:0 siblings: 1:5, 1:6, 1:7, 1:8, 1:9, 1:20 SMTP outgoing traffic goes out 1:8 1:20 is the default so all non-specifically filtered traffic goes out slowly (rate is 0.1kbit) so I know what''s left to filter.
