I found two different articles on microsoft.com which confirms that SO_SNDBUF=0 is valid and is intended to completely disable kernel buffering: * https://support.microsoft.com/en-gb/help/181611/socket-overlapped-i-o-versus-blocking-nonblocking-mode * https://blogs.msdn.microsoft.com/larryosterman/2004/08/06/the-consequences-of-ignoring-nagling-and-delayed-acks/ "If SO_SNDBUF=0, each send() or WriteFile() must wait for an acknowledgement from the other side before returning. (That is the only way for the protocol to implement retransmissions)" ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34130> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
