I really appreciate the energy you bring here and we all love you in some way. However, it's time to ring your Bluehost account manager for violating the contract promising "unlimited" throughput.

Empirical examples below show the real difference: I get < 1.5 Megabit/second when talking in SI units from your server. That's like a factor 65 less than a 100 Mbit Netport. The sole consolation might be that Bluehosts own mirror is even slower than yours. And third example is a mirror with good hardware and a good network (in this case taxpayers money, I know the organization behind). Easier to understand by the "ETA" (acronym for estimated time to accomplish, or so), your 700 Megabyte ISO would have come to me in 65 minutes, while the high-performance mirror would have served it to me in under 2 Minutes, which is a factor 30. Conclusion: Their monthly running cost for the infrastructure is probably more than 30 times the price of what you spend, so you are the winner in price/performance!

Kind regards, 

Florian
