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.
如果您自己不设置初始带宽，Unity Multiplayer 将在启动时根据公式：PacketSize * MinUpdateTimeout 计算出一个默认值。
