Many of us who have the new HT technology P4 processors might have noticed that the new Pc works slower than the older one.
But then I finally discovered a microsoft page that mentioned that the XP sp1 is not geared to handle the Hyper threading technology and gives a very slow performance.

The solution to this problem is that you must directly install SP2 on your XP without instaling SP1.
The performance of your Pc will considerably improve with this.

YOU WILL SURELY UNDERSTAND THE MEANING OF HT.
