Recently I try to use TCP BBR https://github.com/google/bbr/blob/master/Documentation/bbr-quick-start.md My lfs is latest systemd version.
after the below command and reboot sudo bash -c 'echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf' sudo bash -c 'echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf' $ tc qd qdisc noqueue 0: dev lo root refcnt 2 qdisc fq 0: dev enp0s25 root refcnt 2 limit 10000p flow_limit 100p buckets 1024 orphan_mask 1023 quantum 3028 initial_quantum 15140 refill_delay 40.0ms qdisc noqueue 0: dev br0 root refcnt 2 The br0 was not affected. But I can add it manually by 'tc qd add dev br0 root fq' Is it a kernel issue or systemd issue? -- http://lists.linuxfromscratch.org/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
