Optimizing TLS over TCP to reduce latency

The layered structure of the internet, with HTTP on top of TCP, TCP on top of IP, and IP on top of Ethernet, has been crucial for its development. However, this model can cause delays in TLS-encrypted data transmission due to fixed record sizes. To address this issue, Cloudflare modified NGINX to support dynamic TLS record sizes, improving the efficiency of web page delivery over HTTPS connections. The company open-sourced their patch and encourages feedback and improvements from users.
