Server on 100mbit port, wget 15M/s?
I have a server on a 100mbit port (eth0: negotiated 100baseTx-FD flow-control, link ok). When I try to wget e.g. http://download.thinkbroadband.com/1GB.zip or http://speedtest.atlanta.linode.com/100MB-atlanta.... I get net wget speeds about 15M/s or even more, which is more than 120mbit. The file is compressed (tried with gzip). How could this be?

How is 15 Mb/s = to 120 mb/s. If you said 15MB (bytes/second) I might agree but Mb is still bits as is mb it's the b / B that counts! See http://www.endmemo.com/convert/data%20transfer.php for examples.

To be totally pedantic, 100 mbit/sec is actually one tenth of a bit per second or 1 bit every 10 seconds.
m is the abbreviation for milli - meaning one thousandth,
M is the abbreviation for Mega.
So you Ethernet port is 100 Mbps.
Similarly, b stands for bit and B stands for Byte.
Now on a computer there is a transfer function in wget that is actually fetching the data, and there is a separate function that is timing the transfer. The problem may be that the two functions are not properly synchronised. The sample of the number of bytes transferred may occur at the start of one second, but the next sample my be taken at the end of the next second. The elapsed time will actually be nearly two seconds, but the timing function will see only one second so the calculation will produce a value that is higher than it should be. All this assumes that wget is reporting bytes and not bits.
I hope this helps.
