transactions, establishing the initial SSL handshake requires CPU-intensive
public key encryption operations. Most handshake operations are associated with
the exchange of the SSL session key (client key exchange message). When a
client session is idle for some time and is then resumed, the SSL handshake is
typically conducted all over again. With session reuse enabled, session key
exchange is avoided for session resumption requests received from the client.
Session reuse is
enabled on the NetScaler appliance by default. Enabling this feature reduces
server load, improves response time, and increases the number of SSL
transactions per second (TPS) that can be supported by the server.
