Hi Clove, There is no block size as such, in networking. A basic unit of data transfer in networking is called a packet. There is no fixed size as such for a packet, unlike a sector or block size in storage. However the packet size is generally determined by the MTU (Maximum Transmission Unit), or the PMTU of the interface/path. The link speed of the network interface together with the link bandwidth will be a major factor in determining throughput. Another thing that can affect the network throughput is the send/ receive buffer size configured for the OS. In addition there are offload techniques (TSO/GSO/LRO/GRO) which can also make an impact on the throughput.
