Do a search for speed test and then try the different websites. I got
so different values, that I said this is useless.

wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.tar.bz2

Use scp with a big file.

scp linux-2.6.38.tar.bz2.1  address@hidden:/
linux-2.6.38.tar.bz2.1                          4% 3536KB 564.9KB/s

I know it gets less, because of the cache. It is just a simple, how it
could look like.

e.g:http://www.wieistmeineip.at/speedtest/
Download-Geschwindigkeit: [-]
9.060 kbit/s
        
(1.133 kByte/s)

Upload-Geschwindigkeit: [-]     
72 kbit/s       
(9 kByte/s)

I don't believe that my upload is so bad.


BTW, my modem (AVM Fritzbox) gives very good statistics between me and
my Provider

                Empfangsrichtung        Senderichtung
Max. DSLAM-Datenrate    kBit/s  20000   1024
Min. DSLAM-Datenrate    kBit/s  32      32
Leitungskapazität       kBit/s  11088   979
Aktuelle Datenrate      kBit/s  10805   979

The best downloads I get are 1,4 M/s, most times it is about 1,1 M/s.
