Dear Eugene,

Ubuntu doesn't support a randomization parameter via sysctl, I can only enhance
the range for ephemeral port selection. I got a little bit progress:

When I higher the parallel streams to 20, every 10th test or so I can reach
18Gbit. No idea how the source port calculation works exactly but it seems it
works in general, but not in a real predictable manner.
For a backup software working with multiple streams to reach more throughput
it's not garantueed to balance evenly. Seems that Linux does it a bit
different. 

I'll install FreeBSD on the clients after holidays to check if it works better.
Can I leave this open until final testing? 

Thanks for your time! :)
