Do you agree? What is the definition of best? I've saturated a 100 Mbps network link betw= een 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 errors. 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 3= com cards tend to work much better than e.g. Realtek. And a dodgy cable will ru= in your day connection wise.
