Tl;dr I may be entirely wrong, but it appears iTunes store may be throttling bandwidth. Anyone know the full story on this? Here are two images demonstrating my current concern:


To summarize: despite having decent bandwidth, a 47.4 megabyte mp3 takes 15 minutes to download. However, my math indicates that, with that bandwidth, it should take me just under
two minutes to download a file of that size.
((47.4*8)/3.72)/60=1.7
That is
one minute forty two seconds. Accordingly, it seems that iTunes is operating at about 11.5% efficiency, or throttling to the tune of nearly 90%.
How's my math?
