tcp_limit_output_bytes 会限制qdisc/device里的字节数来人为降低RTT/cwnd和降低缓冲区膨胀。 默认是262144. tcp_challenge_ack_limit - INTEGER 限制每秒发送的挑战ACK的数目,就像RFC5961里推荐的一样,增加tcp的健壮性来封堵 In-Window Attacks。 默认是100....

If a log file exceeds the size limit, the oldest data is deleted from the file to store new data. Log files that are generated by using debugfs are one-time files. After data is read from a one-time file, the data is deleted. T1: On a TCP connection, information about a task ...
I'm curious ifmemory.kmem.tcp.limit_in_bytesshould also be considered deprecated in the kernel and, if not, if that option should be re-enabled. MemberAuthor Contributor MemberAuthor MemberAuthor Not sure if anyone is using it (nobody? or we'd get bug reports, I assume), ...
https://unix.stackexchange.com/questions/542712/detailed-output-of-ss-command limit TCP flows with application-limiting in request or responses. 我理解是,这是个 boolean,如果 ss 显示了app_limited这个标记,表示应用未完全使用所有 TCP 发送带宽,即,连接还有余力发送更多。
