Debian9 开启BBR

Debian9 已经开始在各大vps流行起来了,因为自带4.9内核,所以开BBR提速就变成分分钟解决的事情。

echo “net.core.default_qdisc=fq” >> /etc/sysctl.conf
echo “net.ipv4.tcp_congestion_control=bbr” >> /etc/sysctl.conf

保存并生效

sysctl -p

查看是否生效

sysctl net.ipv4.tcp_available_congestion_control

看结果是不是

net.ipv4.tcp_available_congestion_control = bbr cubic reno
