sysctl.conf 使用这个配置

# 内核全局读写上限net.core.rmem_max = 25165824net.core.wmem_max = 25165824# TCP 发送/接收缓冲区大小net.ipv4.tcp_wmem = 4096 2097152 25165824net.ipv4.tcp_rmem = 4096 2097152 25165824# 半连接队列，避免 queue 溢出net.core.somaxconn = 4096# BBR必备net.core.default_qdisc = fqnet.ipv4.tcp_congestion_control = bbr# 国内环境关闭 ECN，防止中间设备丢包net.ipv4.tcp_ecn = 0# 减少握手延迟net.ipv4.tcp_fastopen = 3# 提高 BBR 测速精度net.ipv4.tcp_timestamps = 1# 开启选择性确认net.ipv4.tcp_sack = 1# 视频暂停后重播不降速net.ipv4.tcp_slow_start_after_idle = 0# 自动探测链路 MTU 防止丢包net.ipv4.tcp_mtu_probing = 1# Keepalive（长连接场景）net.ipv4.tcp_keepalive_time = 300net.ipv4.tcp_keepalive_intvl = 30net.ipv4.tcp_keepalive_probes = 5

然后加上 tc 命令

/sbin/tc qdisc add dev enp6s18 root cake bandwidth 950mbit besteffort wash

配置后感觉很丝滑，话说还有其他的推荐不？
