Google TCP Fast Open

[christer12]

Do this router has support for Google TCP Fast Open?
In "normal" Linux can turn on support by:

echo "1"> /proc/sys/net/ipv4/tcp_fastopen

TFO is enabled for client operations by setting bit 0 (with a value of "1"). Bit 1 (value "2") enables TFO for server operations; setting both bits (with a value of "3") enables both modes.

TCP Fast Open would decrease HTTP transaction network latency by 15%and whole-page load time over 10% on average, and in some cases up to 40%.

That won't help. The connection isn't open by the router, but by your PC connecting to the website.

Okey, thanks for the answer

Sorry for bumping this old thread.

I have a process running on the router which I'd like to utilise TCP fast open. In theory kernel after 3.16 should be able to support it, so is there any way for anything after AC86U to enable this option?

I'm stupid. It's hidden...
