More socket connections are required per data stream. Three socket connections are required to accommodate the Remote Network Transport Service that runs on both the media server and the client. Only one socket connection is required for a non-resilient connection.

More sockets are open on media servers and clients. Three open sockets are required rather than one for a non-resilient connection. The increased number of open sockets may cause issues on busy media servers.

More processes run on media servers and clients. Usually, only one more process per host runs even if multiple connections exist.

The processing that is required to maintain a resilient connection may reduce performance slightly.
