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.
