Thank you Mathew, I ' ve done other tests and you are right, my problem 
may be handshake and roundtripped, I do another test in adsl connection 
with one big file  and the wget report is correct. I didn't know than 
other time than transfer is not included in time.

Thank you again for your answer and apologize for the inconveniences. 
You help me to know the true causes of my poor performance in site (is 
not transfer rate).

Best Regards
