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:
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.
