I want to use large socket buffers .I set maximum values for /proc/sys/net/core/rmem_max and /proc/sys/net/core/wmem_max and also made sure the maximum value is high for /proc/sys/net/ipv4/tcp_wmem and /proc/sys/net/ipv4/tcp_rmem. But when i run some ttcp tests i observe that the advertised window of the receiver starts from 5792 bytes even though i use large windows.I read that 2.4 kernels do auto-tuning. Is there anyway i can make the advertised windows larger than 5792 . OR please suggest some resources where i can find the information about the socket buffer implementations. I need this information very much Awaiting a reply from some of you.
