Nice.
Shouldn't faq 6.6.4 be deleted then?

-If you are seeing performance limitations when using a high-speed WAN
-connection transferring lots of data, you may see a performance gain
-by altering the following sysctls:
-<blockquote><pre>
-net.inet.tcp.recvspace
-net.inet.tcp.sendspace
-</pre></blockquote>

-Try a value like 65536 instead of the default of 16384.
-Note that very few will see any benefit from this.
-Don't adjust this unless you are actually seeing performance below what
-you expect.
