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. Cheers Vivek On Thu, Dec 5, 2013 at 4:52 PM, Robert Clove <cloverobert@gmail.com> wrote:
Hi All,
Can anyone please through some light on what is block size in networking and how does it effect the TCP/UDP throughput?
Thanks Clove
