I have been using the Java based versions of the speed test.  At this point I 
have had some Sprint people get in contact with me so I will see what they 
find.  Thank you for all your help to everyone.

I am currently having problems get upload bandwidth on a Sprint circuit. I 
am using a full OC3 circuit.  I am doing fine on downloading data, but  
uploading data I can only get about 5Mbps with ftp or a speedtest.  I have 
tested against multiple networks and this has stayed the same.  Monitoring 
Cacti graphs and the router I do get about 30Mbps total traffic outbound, but 
individual (flows/ip?) test always seem limited.  I would like to know if 
anyone else sees anything similar, or where I can get help.  The assistance I 
have gotten from Sprint up to this point is that they find no problems.  Due 
to the consistency of 5Mbps I am suspecting rate limiting, but wanted to 
know if I was overlooking something else.
