In your case, 1.53 GB in 10 seconds, 12.24Gb in 10 seconds, 1.224Gb/second. I 
wonder what’s the 1.32-1.224 = 96 Mb/sec is for ?

The amount or volume of data transferred in a given amount of time. 1000MB in 
10 seconds is 100MB (roughly 800Mb) per second.

Subject: [Iperf-users] How iperf works? 

Hi all,

I want know how iperf works for bandwidth.

I know it based on a client-server-modell but what I don't know is, how it 
calculate the throughput?

For example:

The client send 10 sec data to the server - how the client know the throughput?

 

And I test iperf using :

Client :

Ø  Iperf –c [iperf_server ip]

 

Server :

Ø  Iperf –s

 

 

Result from server :

[ ID] Interval       Transfer     Bandwidth

[1912]  0.0-10.0 sec  1.53 GBytes  1.32 Gbits/sec

 

 

Is the Bandwidth using roundtrip to compute ?
