Thanks for the links, it seems many are having the problem across different MB 
(which are all Asus) on all BSDs.  I also found that forcing speed instead of 
letting ifconfig on auto fixes part of the problem.

In fact:
clk01a# ifconfig -m sk0
sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        inet 192.168.1.100 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::211:d8ff:fe44:15f4%sk0 prefixlen 64 scopeid 0x1
        ether 00:11:d8:44:15:f4
        media: Ethernet 100baseTX <full-duplex> (100baseTX 
<full-duplex,flag0,flag1>)
        status: active
        supported media:
                media autoselect
                media 1000baseTX mediaopt full-duplex
                media 1000baseTX
                media 100baseTX mediaopt full-duplex
                media 100baseTX
                media 10baseT/UTP mediaopt full-duplex
                media 10baseT/UTP

forcing it on 100baseTX (full duplex) :

ifconfig sk0 media 100baseTX mediaopt full-duplex

And I get no more delays before connection, speed is about 93%(RX) and 
63%(TX). which is a great improvement.

Your download speed : 6162099 bps, or 6017 kbps.
A 752.2 KB/sec transfer rate.
Your upload speed : 511465 bps, or 499 kbps.

This is a start and I suggest that everyone with a sk0 and that problem try 
forcing it on 100mbps and do some test. I don't want to be just lucky :).

Thanks,
Nicolas.
