TCP Window size question

Jan 29, 2008 3 Replies

Hi



Can we change these files to tune network performance in embedded linux ?



/proc/sys/net/core/rmem_max /proc/sys/net/core/wmem_max /proc/sys/net/core/rmem_default /proc/sys/net/core/wmem_default



Does it control recieve(RX) or send (TX) performance ?



If it is a P2P or client-server traffic testing , should we change the other device TCP Window size too ?



Is there suggested value for Internet or LAN point device ?



Thank you


Try end-to-end Qos Implementation. Many techniques are there to bring in improvement. DiffServ and MPLS look gud.

If you are planning to play with TCP window size, be careful with the sliding window algorithm.

The default window size settings on Linux should be OK for most applications. The only exceptions are satellite links.

BTW, comp.protocols.tcp-ip would be a better newsgroup for this question.
