Hi,

I'm trying to find answers to a problem that I'm currently experiencing in all my servers. Downloads offered over HTTPS are at least 4 times slower than those delivered over HTTP. All these servers are running nginx/1.6.2. Here is my nginx.conf in case someone have experienced something similar and could give me a hint. By the way, when I say 4 x slower I'm being optimistic... I can download 4-5MB/s over HTTP while https download are 600-700kb/s the fastest I've seen.

user www-data;
worker_processes 2;
pid /run/nginx.pid;
worker_rlimit_nofile 4096;

events {
worker_connections 1024;
multi_accept on;
use epoll;
}
