VPS开启bbr拥塞控制算法
1. 先看是否为 bbr
sysctl net.ipv4.tcp_available_congestion_control
2. 若未显示 bbr，则执行下述命令
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p
sysctl net.ipv4.tcp_available_congestion_control
echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p
