First of all, tcpmux daemon is involved only in the connection
establishment phase. After that it hands the connection to the
application and gets out of the way. Therefore, performance-wise,
tcpmux is equivalent to simple tcp transport.

If you want to look at the code, the connection hand-over is done here:
