I'm using the code from lartc.org: tc qdisc add dev eth0 handle ffff: ingress tc filter add dev eth0 parent ffff: protocol ip prio 50 \ u32 match ip src 0.0.0.0/0 police rate 500kbit \ burst 10k drop flowid :1 I've tried rates of 1Mbit, 10Mbit, 100Mbit. I've tried bursts of 1k, 10k, 100k, 1000k. Nothing seems to make any difference. The test download starts at about 20Mbytes/second - then keeps on slowing down and stalling intermittently all the way down to 6kbytes/second. Then it bobs up and down, stalling all the time, between 5kbytes/second and 17kbytes/second. There seems to be absolutely no relation between the rate I set and the resulting download rate. I'm testing on two VM's. With no traffic shaping on, I get about 36 megabytes/second clean speed between the two vms. Kernel on both sides is 3.8.4. I'm only applying traffic shaping on one of the vm's. Any suggestions would be much appreciated. I ran out of ideas so far. I've reread the tc-htb man page, searched google on the ingress queue - but can't see what am I missing.
