other tests with dragonfly

[Wojciech Puchar]

as my friend advised me, i did flood test - generated lots of random UDP 
packets with size between 52 and 100 bytes.

Actually low end ethernet card in my laptop was a limit (rl), but compared 
FreeBSD 10 with custom kernel and dragonfly 3.6 with generic kernel (that 
have diagnostics check compiled by default).

dragonfly used about 3 times less CPU.

no tests on gigabit or 10 gigabit ethernet and multicore machine for now.

quite good.

CPU load on more normal cases (like transfering files using rcp) is lower 
too, but difference is smaller like 1.5-2 times.
