Why is the FreeBSD TCP/IP stack the best?

[Ed Flecko]

Hi folks,
I have several networking books (TCP/IP, Network Security, etc., etc.)
and it seems that several of them discuss TCP/IP in different
scenarios.

One of the common discussions of different OSes are their own
implementations of the TCP/IP stack. Most of the authors seem to agree
that while different OSes have their pros and cons, most seem to agree
that in terms of pure, network performance, no OS is better that
FreeBSD!

O.K., now you've got my curiosity...

1.) Do you agree?

2.) What makes the FreeBSD TCP/IP stack so much better and or
different than other OSes???

3.) Are there any good resources (URLs, books, etc.) that highlight
the differences???

Thank you,
Ed
