Slow mp4 buffer over SSL !!

[shahzaib shahzaib]

Hi,

We've shifted our static content to SSL recently and found that mp4
streaming is drastically slow over SSL ( around 90KBps on 4Mbps connection)
and if we test the same video over HTTP it gives us full 400+KBps speed.
Here is the SSL config :

server {
        listen  443 spdy;
        ssl on;
        server_name cw004.domain.net www.cw004.domain.net;
          ssl_certificate /etc/ssl/certs/domain/domain-combined.crt;
          ssl_certificate_key /etc/ssl/certs/domain/domain.key;
          ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
          ssl_ciphers

        location / {
            root   /videos;
            index index.html index.htm index.php;

}
location ~ \.(flv)$ {
                flv;
                root /videos;
                expires 7d;
                include hotlink.inc;
                }


                include thumbs.inc;

#location ~ \.(jpg)$ {
#                root /videos;
#                try_files $uri /files/thumbs/no_thumb.jpg;
#                }


        location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
                expires 1y;
                log_not_found off;
        }

 $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

        location ~ /\.ht {
            deny  all;
        }
}

-------------------------

Is there optimization being missed for SSL ?

Thanks.
