Network Bandwidth for License Server

FlexNet Publisher sends relatively small amounts of data across the network. Each transaction, such as a checkout or checkin of a license, generally transfers less than 1 KB of data. This means that FlexNet Publisher can be effectively run over slow networks (such as dial-up SLIP lines) for small numbers of clients.

For a large number of FlexEnabled applications (hundreds), each of which exchange heartbeat messages with the vendor daemon, the network bandwidth used may become significant. In this case, run the FlexEnabled application and server on the same local area network, and run multiple license servers if required. Users can use a license search path in the LM_LICENSE_FILE environment variable to have effective access to both servers. Enterprises can experience a performance issue when there is slow network communication or if FlexEnabled clients are using a dial-up link to connect to the network.

When you are using lmadmin, which uses HTTP, you need to consider the clients that connect to the lmadmin user interface. Depending on the number of clients and the frequency of the page refresh, they can impose a significant burden on network traffic.
