Hi Fan !
FTP may useful to test a low-speed wan interface, but high speed Campus ...
In the latter case, your PC not strong enough to receive 12,5Kbytes/sec
(100/8) The main reason is Harddisk writting speed.
In the first case, the result may lower a bit in compare to Bandwidth/8,
because of some kinds of header. FTP only count speed base on (amount of
data)/sec
There are some software that use to calculate the utilization of bandwidth
like MTRG, or solarwind ...
Cheers

Subject: How fast can Ftp speed reach?

that?
