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.

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

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

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
