Because now I have 2 intelligent machines with gigabit LAN speed.
BUT KU lan has only 100 mb connection.

Because I am too intelligent so this morning I burn 7 UTP heads and waste 
several hours to make cross direct UTP cable to connect to pc with gb lan.

The result is cross cable UTP I made has only 100 mb speed.

While my stupid son simply use old cable w/o cross link and he got GB 
speed as below test:

=============================

So, the conclusion is too intelligent become tooo stupid in some case 555.

Reason I burn 7 UTP heads while it need only 2 heads to make a cross line 
because instrument I buy a new ONE is bad instrument and finally I use 
several years old instrument and it work wonderfully.
So, don't trust new instrument.

ps. it was impossible to get full 1 GB transfer even you have GB speed.
At most you can get is only 62 % performance 555555555
