Linux 内核提供了 net.ipv4.tcp_moderate_rcvbuf 参数来控制 TCP 接收缓冲区大小的自动调整。如果此参数被禁用或设置不当,系统可能无法根据当前网络条件动态调整接收缓冲区大小,从而影响网络性能并导致丢包。 为了优化 net.ipv4.tcp_rmem 参数并减少丢包问题,可以采取以下措施: 合理设置接收缓冲区大小:根据系统的内存资...
参数net.ipv4.tcp_max_tw_buckets可以调整内核中管理 TIME_WAIT 状态的数量,当实例中处于 TIME_WAIT 及需要转换为 TIME_WAIT 状态连接数之和超过了net.ipv4.tcp_max_tw_buckets参数值时,message 日志中将报错time wait bucket table,同时内核关闭超出参数值的部分 TCP 连接。您需要根据实际情况适当调高net.ipv4.t...
tcp_moderate_rcvbuf - BOOLEAN If set, TCP performs receive buffer auto-tuning, attempting to automatically size the buffer (no greater than tcp_rmem[2]) to match the size required by the path for full throughput. Enabled by default. tcp_mtu_probing - INTEGER Controls TCP Packetization-Layer ...
