What is the definition of best? I've saturated a 100 Mbps network link between
two FreeBSD machines using nc(1) without the CPU's breaking a sweat. So it's
definitely Good Enough wrt speed. And I don't see many dropped packets or
However it does not follow that there aren't other operating systems capable
of the same.
And it depends to a significant degree on the network hardware. Intel and 3com
cards tend to work much better than e.g. Realtek. And a dodgy cable will ruin
your day connection wise.
