Description

Now the value of PacketReceiver#MAX_PACKET_SIZE is fixed and the size is 16M. This value should be configurable to facilitate better performance in different environments. For example, when the network environment is poor, or the machine quality is not good, and the hard disk quality is not good, this value should be set below 16M, such as 8M, which will be more conducive to the stability of the cluster.
