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).<br>
<br>
dragonfly used about 3 times less CPU.<br>
<br>
no tests on gigabit or 10 gigabit ethernet and multicore machine for now.<br>
<br>
quite good.<br>
<br>
CPU load on more normal cases (like transfering files using rcp) is lower too, but difference is smaller like 1.5-2 times.<br>
