Nginx 1.6.0 + spdy performance testing

I need to evaluate if using spdy will be good for my website but i’m
trouble setting everyting up. While using the chrome benchmark extension
an error message stating that it was not possible to use spdy apeared.
made me believe that there might be something wrong with my
However, except for two warnings, tells me that spdy is
enabled. In (2) you can see what what those warnings are.

I have two questions:

  1. is there anything wrong with my configuration?
  2. is there any other tool that can be used to run performance tests?
    (please only suggest tools that u have tested yourself).

Ps.: chrome://net-internals/#spdy also shows that spdy 3.1 is enabled.

I have posted my configuration file in (2) but for convenience here it

server {
listen 80;
listen 443 ssl spdy;


ssl_certificate /etc/nginx/ssl/tulio.crt;
ssl_certificate_key /etc/nginx/ssl/tulio.key;

if ($ssl_protocol = "") {
        rewrite ^  https://$server_name$request_uri? permanent;

root /usr/share/nginx/html;
index index.html index.htm;

location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ =404;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules

I add an extra header, just for those who don’t understand spdy…

add_header Alternate-Protocol “443:npn-spdy/3.1”;

and specifically set up ssl protocols/ciphers and ocsp stapling but I’d
suggest that it’s a limitation of the benchmark that you’re hitting.

Using something like does show pretty waterfalls of the
differences that delivering sites over spdy makes.

Sorry, pretty useless post really (:
