The network packet size option sets the packet size (in bytes) that is used across the whole network. Packets are the fixed-size chunks of data that transfer requests and results between clients and servers. The default packet size is 4,096 bytes.
Do not change the packet size unless you are certain that it will improve performance. For most applications, the default packet size is best.
