Hi Eduardo, don't expect you will be able to download a single connection at 40Mbps. Your test will be limited by the latency. You can do some tweak in the TCP but it will not improve too much considering the latency between BR and US. Here are two links which can give you some directions: http://en.wikipedia.org/wiki/Measuring_network_throughput http://www.speedguide.net/bdp.php HTH ./diogo -montagner On Sun, Feb 20, 2011 at 3:41 AM, Eduardo Schoedler <eschoedler@viavale.com.br> wrote:

Hi everyone.

This is my first post here in Nanog. First of all, sorry my bad english -- I'm Brazilian.

We are activating a new transit connection with 40 Mbps and I need to test it, but here in Brazil all the international transits are weak. I'm looking for a server that I can download/upload with full speed at New York or Miami, places that this transit have presence in some NAP/IXP (interconnections). Can be one url with a file of 1GB 'dd' generated file, but the server need to have this bandwidth avaliable.

Can someone help me ?

Thanks in advance.
