Hello!
I would say that current implementation of Kernel TLS in OpenSSL will give
huge overhead because of additional syscall for every frame and it's header,
it doesn't matter if it's sendfile or not. Without sendfile it's actually
5% worse
in my tests. That's why it's better to disable Kernel TLS

Hello,
I have tested the nginx with the patch
https://hg.nginx.org/nginx/rev/65946a191197 (SSL: SSL_sendfile() support
with kernel TLS.) following the nginx blog article
https://www.nginx.com/blog/improving-nginx-performance-with-kernel-tls/
And it sort of works, but I have bad performance
