16 cores but packet generation is too slow

[GoogleCodeExporter]

Hello. How can I use all cores in Linux for optimizing packet generation?

CPU:2xIntel(R) Xeon(R) CPU E5620  @ 2.40GHz
PREMIUM NETWORK: 100 mb/s

129583 packets in 1.000517 seconds too slow...

Hello,

Bonesi is only single threaded. If you want to send more packets in parallel, 
just start it multiple times.

Please note, that you need to send very small packets in order to not fill up 
your bandwidth.

Also note that performance does not only depend on your CPU but also on network 
hardware, motherboard I/O and so on.

For example, if I run bonesi on a single core of my PC (AMD Phenom II X6 1100T) 
I can get up to 150,000 pps (ICMP, 1 byte). If I run it on 2 cores I can 
transmit up to 300,000 pps and then there will be no improvement using 3,4,5 or 
all 6 cores.

If you want more packets you should consider using more physical hardware, this 
scales usually better, even if you are using old machines (even 5-10 year old 
machines can generate up to 100,000 pps).

Thank you very much, sir! Also I learned how to use all cores in Linux with 
"taskset" command. During 1 sec it generates 676.000 pps.
