Linux Kernel autotuning TCP

On a RHEL 5.5 box how would i check to see if the autotuning is turned on for TCP parameters?

 

Thanks

Re: Linux Kernel autotuning TCP

It is enabled by default.

Run:

cat /proc/sys/net/ipv4/tcp_moderate_rcvbuf

 If the output is "1", then autotuning is in effect for the receive side. For the sending side, the autotuning has been always enabled for many years.

 

The source of my information.
