Hi Everyone,

Has anybody done anything for that?

Hey @Mohamadgh - sorry, not sure how I missed this thread way back then.

Caddy doesn’t support TCP Fast Open; I’m waiting until Go supports it, maybe 1.10:

However, I’m placing bigger bets on BBR. You can try it now on Linux:

TCP_FASTOPEN reduces the time-to-first-byte (on both sides). (Think: first bytes sooner.)

TCP_BBR is a congestion control, which results in better bandwidth utilization (think: faster downloads).

Is there way to enable Tcp Fast Open for Caddy Servers?
I see that Go supports it now.
