Hi,

Wanted to understand the Behaviour of TCP reception when The Window Size is Increased. Should The Speed at which the Packets are Transmitted by the Server increase??? Assuming that there is processing the Packets very fast.

The speed can do three things when the window size is increased: it can go up, it can stay the same, and it can go down. It all depends on the latency and bandwidth of the links between client and server. The more bandwidth and the higher the latency, the higher the window size needs to be.

Performance goes up when the line has a high latency and a lot of bandwidth and the window increases. If the line has different speeds (lets say 1GBit and 10Mbit) in different segments the device that has to break down the fast speed to the slow speed can be slammed shut with packets if the window size increases, which leads to packet drop and thus to a slower speed than before.
