>Could someone explain me the real network data throughput (without

>18-10-1999 23:01:42   ANE4966I (Session: 327, Node: RIJSAP90)  Network data
>
>                       transfer rate:        34,935.96 KB/sec
>
>Please observe :
>
>Our server is connected with a 100 Mb/s (Mega bit) connection. This is 100
>Mb per sec!
>Now since there are 8 bits in a Byte this means that the transfer rate of
>the link is 100/8 = 12.5 MB/s (Byte)
>Or  12,800.00 KByte (The multiplying factor for network data is 1024
instead
>of 1000, but the link is based on 1000 so there are a few minor errors in
>the computations.)
>
>Now let's compare this theoretical maximum to reality shall we.

>Theoretical maximum             12,800.00 KB/sec         43.9 GB/Hour
>Practical reality                        10,000.00 KB/sec        34.3
>GB/Hour
>in our example                  34,935.96 KB/sec        119.9 GB/Hour
>
>As you can see, the  values greatly exceed the theoretical maximum.
>How is this possible?
>or do we misinterpreted "Network data transfer rate: 34,935.96 KB/sec" ?
