You've provided a python-based speed test against a system in Phoenix Arizona followed by a wget-based download from a site in Chantilly, VA. That doesn't really demonstrate a whole lot. Can you more thoroughly describe or better demonstrate your experience of slow download speeds?

sftp is normal speed, just all wget and any tcp6 connections are all slow.

Well, it's highly unlikely that the performance problem you are experiencing is inherent to the wget utility across either IPv4 or IPv6 connections. It's possible that the utility is problematic, but since it's such a commonly used utility (I use it all the time and have no troubles), it's unlikely. What happens if you use wget to retrieve a file from a system with both IPv4 and IPv6 addresses, using the -4 and -6 options with wget to force the use of each protocol in separate download attempts? Can you use wget to demonstrate slowness when using IPv6 in particular?
