I was trying to download some files off of a server that I recently started renting. It is a dedicated server located in Paris-FR. I believe the box is in online.net's datacenter. I am renting it from OneProvider.
Downloading files using http gave me unsatisfactory speeds. On the server I set up a SimpleHTTPServer using python and the client is a laptop i norway. The speeds i was seeing ranged between 3.2Mb/s and 6.4Mb/s
I set up a Iperf server on the dedicated box and connected to it using the same client and got the following results
------------------------------------------------------------
Client connecting to 195.154.222.67, TCP port 5001
TCP window size: 208 KByte (default)

The client is on a 100/100 connection and on a wired network. I have done some speedtests using speedtest.net to servers locted in Paris-FR and the speeds range from 38Mb/s to 64Mb/s.

First, are you sure you didn't confuse megabytes with megabits or vice versa?
If you're sure that part is correct, then:
Try other software like apache, nginx, scp, ftp, whatever... it's won't take long. Maybe it's just your python script that's responsible. Same on the client side - try a browser, wget, curl, ftp, scp, whatever... Try http (and maybe https) over a different port like the one iperf is using. If you get different speeds with different ports/protocols consistently, talk to your provider. That's not supposed to happen.
If you want a second opinion over
iperf
you can usenetcat
