>Description:
	

The tuning man page says:

     65535 and stick with that if the performance is acceptable.  In extreme
     cases you may have to turn on the net.inet.tcp.rfc1323 sysctl and
     increase the buffer size to values greater then 65535.  This option turns
     on the window sizing extension to the TCP protocol.  We do not recommend
     that you use this option unless you absolutely have to because many hosts
     on the internet can't handle the feature and may cause connections to
     freeze up.

However, in /etc/defaults/rc.conf, these TCP extensions are turned on.
I'm assuming this recommendation is out of date?
