Security

Encryption CiphersOK
Public Key Size2048 bitsKey sizes 1024 bits or larger are considered secure. Be aware that unnecessarily large key sizes will slow down the connection establishment.
Secure RenegotiationYes
ProtocolsOKSSLv3, TLSv1

 

Performance

HTTP KeepaliveNoEnabling HTTP Keep-Alive will allow subsequent requests to be served faster, without the need to establish a new SSL/TLS connection.
SSL Session CacheYes
TLS Stateless ResumeYes
SSL Handshake Size4007 bytesA smaller SSL handshake means a faster connection. Reducing the number & size of certificates in your chain, and reducing the size of the public key will reduce this.
