If '(sudo) sysctl net.ipv4.tcp_moderate_rcvbuf' returns 1 then the kernel automagically tunes the necessary buffers so you don't need to muck with tcp_rmem, tcp_wmem and the like. (Linux enables TCP Windows Scaling by default since 2004.) If autotuning is enabled and '(sudo) sysctl net.ipv4.tcp_moderate_rcvbuf' returns 1 then the TCP window size is autotuned as well. (See the standard http://www.psc.edu/networking/projects/tcptune/ and http://www.frozentux.net/ipsysctl-tu...l#TCPVARIABLES texts.)
