Internet speed

[Jomapil]

Hello, everyone.

I want to put the following problem:

My contracted speed is 50 Mbps.
I performed several tests of my internet speed at the same moment ( some seconds of interval ) with three sites: ( The results are in Mbps - Megabits per second )


Down Up
http://www.dslreports.com/speedtest?flash=1 --------------------------------------------- 3.77 1.94
http://www.abeltronica.com/velocimetro/pt/?idioma=pt&newlang=pt&favoritos=1 ------- 28.1 2.45
http://www.speedtest.net/ -------------------------------------------------------------------- 48.35 2.58

What is, after all, my true speed?


Thanks for your help and explanation.

Good bye.

your speedtest.net download report of 48.35 pretty much confirms your isp 50mbps line. upload is not as good at 2.5 but more than enough for most people aren't running webservers.

The other differences are probably due to physical location of the server and the number of internet "hops" it has to take.

If speedtest has a local server in portugal, the connection should be faster than to one you were connecting to in USA for example

If the other end cannot send data fast enough for whatever reason, it becomes the bottleneck, not your connection

Thanks aedipuss and poisondeathray for your explanation.

Another question about the same subject:

The PC of my son is connected to the Net by the same router. The length of his cable is about 10 meters such as mine.
But my speed is 48 Mbps and he has only 18 Mbps. Why this? It has to see with the diferent configuration of his PC?

Good bye.

How were the speeds measured? To the same server?

What else was using bandwidth concurrently? i.e. if you were surfing or using the same connection at the same time, it will "eat up" part of the total bandwidth, limiting the amount of bandwidth available for your son's connection.

Yes, the speeds were measured at the same server.
And the conditions of the measures of those PCs were strictly the same. It only remains the differences of the PCs configurations. Will this be the reason?

Thanks again, poisondeathray.

Good bye to everyone.
