Web30 jul. 2014 · If the receive window is 64k and the cwnd opens up to 48k, but the send buffer is 32k, we’re not able to fill the available send window of 48k. In this case we’re limited by the send buffer size. Summary Many factors control the sender’s throughput. The sender can’t send more data at one time than the advertised receive window. WebHere we can see this socket has Receive Buffer 369280 bytes, and Transmit Buffer 87040 bytes. Keep in mind the kernel will double any socket buffer allocation for overhead. So a process asks for 256 KiB buffer with setsockopt (SO_RCVBUF) then it will get 512 KiB buffer space. This is described on man 7 tcp. fitted rear seat covers
