Keep Installer on Client System—Enable to allow permanent client installation on the remote
computer. Enabling disables the automatic uninstalling feature of the client. The client remains
installed on the remote computer for subsequent connections, reducing the connection time for the
remote user.
Compression—Compression increases the communications performance on low-bandwidth links
between the security appliance and the client by reducing the size of the packets being transferred.
On broadband connections, compression might degrade performance.
Datagram TLS—Datagram Transport Layer Security (DTLS) allows the AnyConnect Client
establishing an SSL VPN connection to use two simultaneous tunnels—an SSL tunnel and a DTLS
tunnel. Using DTLS avoids latency and bandwidth problems associated with SSL connections and
improves the performance of real-time applications that are sensitive to packet delays.
Compression and DTLS are mutually exclusive. If you enable both, DTLS is inactive for the
client connection.
