For my site , ssl seems to be slow even though i got A+ on sslabs
(implemented ocsp stapling, Forward Secrecy , spdy)
Here is the result from pingdom
http://tools.pingdom.com/fpt/#!/cc2MfH/https://www.filterbypass.me/
Notice the high connect time and high ssl negociation time
Here is my nginx conf
server {
listen 443 spdy default_server; #Change to 443 when SSL is on
ssl on;
ssl_certificate /etc/ssl/filterbypass.me.crt; #(or .pem)
ssl_certificate_key /etc/ssl/filterbypass.me.key.nopass;
ssl_client_certificate /etc/ssl/intermediate.crt;
ssl_protocols SSLv3 TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers
ECDH+AESGCM:DH+AESGCM:ECDH+AES256:DH+AES256:ECDH+AES128:DH+AES:ECDH+3DES:DH+3DES:RSA+AESGCM:RSA+AES:RSA+3DES:!aNULL:!MD5:!DSS;
ssl_prefer_server_ciphers on;
ssl_buffer_size 8k;
ssl_session_cache shared:SSL:10m;
ssl_dhparam /etc/ssl/dhparam.pem;
ssl_session_timeout 10m;
ssl_stapling on;
ssl_stapling_verify on;
ssl_trusted_certificate /etc/ssl/trustchain.crt;
resolver 8.8.8.8 8.8.4.4;
add_header Strict-Transport-Security "max-age=31536000;
includeSubDomains";
#rest of config goes here
}
