Description

Hi,

Instead of iterating everything CloudFlare? has already written, their blog post is here:

https://blog.cloudflare.com/optimizing-tls-over-tcp-to-reduce-latency/

And the patch is here:

https://raw.githubusercontent.com/cloudflare/sslconfig/master/patches/nginx__1.11.5_dynamic_tls_records.patch

In short, it enables nginx to, instead of having just a static ssl_buffer_size, have the initial requests fit in the least amount of TCP-segments possible, and size it up to 3x segment size, on to the full ssl_buffer_size later. This can greatly speed up TLS.
