That is why. The RTT to the source can not be larger than the minimum
buffer size in the transport path. Otherwise the speed will start
decreasing.

Since a lot of ISP equipment only has tiny buffers you will generally be
unable to get great downloads from sources far away.

The other option is huge buffers which gives you better speed but with
buffer bloat issues.
