BSD sockets setsockopt option to avoid waiting for acknowledge before next send
问题 I am trying to send some KBytes of data trough Ethernet with a proprietary simple raw TCP protocol. Standard Windows configuration requires two (2) packets received before returning an acknowledge packet, unless you modify the registry with TcpAckFrequency = 1, in which case one received packet is enough to send back the acknowledgement, or otherwise anyway you will get an ACK after TcpDelAckTicks * 100 = 200 ms by default (this is another registry key). This is a problem if I send the data
