[netperf-talk] -s parameter doubt

[Otavio Augusto]

I was reading and test some netperf parameters and I'm doubt with the '-s'
or -S'.

Example:
 netperf -H 127.0.0.1 -l 2 -- -s 10k -S 10k
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 127.0.0.1
(127.0.0.1) port 0 AF_INET
Recv   Send    Send
Socket Socket  Message  Elapsed
Size   Size    Size     Time     Throughput
bytes  bytes   bytes    secs.    10^6bits/sec

 20000  20000  20000    2.00     1977.44


Why it used the double? I set 10k but it use 20k?

Thank You.
