Gets or sets the bandwidth in bytes per second that can be used by Unity Multiplayer. No traffic over this limit is allowed. Unity Multiplayer may internally reduce the bandwidth it uses due to flow control. The default value is 1500MB/sec (1,536,000 bytes per second). The default value is intentionally a large number to allow all traffic to pass without delay.
If you do not set the initial bandwidth yourself, Unity Multiplayer calculates a default value when it starts according to the formula: PacketSize * MinUpdateTimeout.
