float MaxSendRate
Maximum sustained transmission rate in Gbit / s.
The default value is 1 Gbit/s.
This is to control transmission of larger packages over the network. Without a limit, it is possible for packet data loss to occur because more data may be sent then may be supported by your network card.
Adjust this value higher or lower depending on your network capacity.
