Enable TCP Fast Open in Edge browser to make pages load faster

Microsoft Edge browser on Windows 10 v1607 and later offers a feature that can make web pages load faster.  To activate this feature, you will have to enable TCP Fast Open, which is an extension of the TCP Protocol that enables data exchange during TCP’s initial handshake. When TCP Fast Open is enabled, data can be sent before the connection completes, so that responses will arrive mush faster.

Fast Open protocol is a new mechanism that enables data exchange during TCP’s initial handshake. In doing so, TCP Fast Open decreases application network latency by one full round-trip time, decreasing the delay experienced by such short TCP transfers, says Google.
