The size of the window is less than or equal to the buffer size.
Their buffer size is 8MB or 16MB depending on the drive model.
Increasing buffer size will help, but also increase latency.
The buffer size was increased and the first connection was flawlessly made.
Increasing buffer size or quitting other application helps to keep playback smooth.
In general, buffer size will need to be scaled proportionally to the amount of data "in flight" at any time.
This amount depends on the receiver's buffer size and maximum segment size.
This assumption is generally met if each device is designed with adequate buffer sizes.
So for example when you have a buffer size, the variable should be named "cb", which means "count of bytes".
The performance problem was attributed to the small buffer size used in the controller.
