Hi

I was trying to measure the bandwidth using tcp connection.
The client simply sends junk from one end and the server receives
it. In between sending data, the client measures the time taken
to send some N bytes (say 30 KB) of data. The start of measurement
is when the client stats sending data, and the end, when the
server sends the final acknowledgement.

This measurement I am doing for a 35 Kbps. I never got a measurement
above 28 Kbps. But when I tried with the tool iperf, the bandwidth
meausred was always less than 4 Kbps!

What perplexes me is nothing but that the program which I wrote
should always underestimate the actual bandwidth because of the
tcp headers not taken into account while measuring; but, iperf, a
bandwidth measurement tool, gives a measurement much lower than that
!!!!

Can anyone please help me ...?

Thanking in advance.
