The hidden cost of QUIC and TOU (2016)
Some new proposed protocols will encrypt the transport layer headers. Encryption is good, so more encryption must be better, right? Unfortunately there's going to be a huge hidden cost that'll be paid by anyone troubleshooting networking problems.

Increase HTTP performance by fitting in the initial TCP slow start window
Did you know that if your site’s under ~12kb the first page will load significantly faster? Servers only send a few packets (typically 10) in the initial round-trip while TCP is warming up (referred to as TCP slow start). After sending the first set of packets, it needs to wait for the client to acknowledge it…
