[netperf-talk] Why is the send and recv socket size bytes getting doubled by default

[Richard Jose]

Hello Everyone,

I am running netperf on a ubuntu-10.10 server and I am using the 
following command:
netperf -H mav1-vm2 -l 60 -t TCP_STREAM -- -m 8192 -M 8192 -s 8192 -S 
8192

And this is the result:

TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to mav1-
vm2.lab.xyz.com (192.xxx.xx.xxx) port 0 AF_INET
Recv Send Send
Socket Socket Message Elapsed
Size Size Size Time Throughput
bytes bytes bytes secs. 10^6bits/sec

16384 16384 8192 60.00 33.31

I do not understand why the socket size is getting doubled when the 
netperf command is run inspite of using the -m and -M options.

Please help me in understanding what exactly is happening here.

Thanks,
Richard
