Enable “TCP Fast Open” for Microsoft Edge to Speed Up Browsing

Microsoft Edge supports TCP Fast Open, a specification to speed up the opening of successive TCP connections faster between clients and servers, reduces the round-trip delay and lower the latency in the start of data transmission. This option is disabled by default in Microsoft Edge, but you can enable it via the about:flags page, to speed up browsing.

Type “about:flags” in Edge browser Address bar and press ENTER.

Scroll down to Networking section, and enable the checkbox for “Enable TCP Fast Open”
