Main question:
When I first installed windows 10, there was a setting "tcp fast open" in the edge browser, and now it's gone, how can I enable it?
Backstory:
When I first tried edge, I thought it was a laggy piece of you know what, but after googling around, I bumped into a post where a person says that if you type "about:flags" into search bar in edge, and enable the "tcp fast open" feature, your browser will work faster. I did what that person said and it worked! Everything was loading super fast like in any other modern browser.
But after some update this feature is gone. One would assume that since it was an experimental feature, it's probably enabled by default already and isn't an experimental feature anymore, but according to my browsing experience, it's not the case and 60% of the time pages take 13 seconds to load (I counted it every time).
So, is there still a way to enable tcp fast open?
Optionally, could someone tell me what this feature does and how it works? I'm really curious to know!
TCP Fast Open is a well-known technique. Just search for it and you will find numerous resources for research. // It used to be an experimental feature back in 2016. It is most likely no longer experimental by now. You can always compare it with a different browser, like Firefox (enable
network.tcp.tcp_fastopen_enable). – Daniel B – 2018-03-12T18:52:52.523@DanielB do you know how to enable it in edge? It seems like it's disabled now, because edge is super slow. – None – 2018-03-12T18:58:02.643
It’s either on by default or removed. Simple as that. Keep in mind that it was only ever available on Insider Builds. If you have latency issues with your internet connection they may have gotten worse. – Daniel B – 2018-03-12T18:59:36.173
@DanielB everything works super fast in chrome, but not in edge on my end, so I don't think it's my internet connection issues. Too bad you can't enable it anymore... – None – 2018-03-12T19:01:48.243
Chrome doesn’t even support TCP Fast Open on Windows. – Daniel B – 2018-03-12T19:03:16.253
@DanielB oh, I guess edge sucks then, lol. – None – 2018-03-12T19:04:32.123
@DanielB where do I need to type network.tcp.tcp_fastopen_enable to enable this feature in firefox? – None – 2018-03-12T19:18:48.793
About page, same as any configuration option enabled, manually – Ramhound – 2018-03-13T00:22:20.127
EdgeHTML 16 doesn’t support TFO, due to complaints, Microsoft disabled it after previously enabling it in EdgeHTML on 15. What you want (Enabling TFO on the current version of Edge) isn’t possible – Ramhound – 2018-03-13T00:55:34.803
