First of all operating system XP pro, with the service pack 2. On a dual Pentium 4 machine. Cable modem.

I have heard or understood the Windows service pack 2, is part or possibly is the problem for slowing down the upload, I am trying to applaud some video tutorials, in my connection speed becomes very slow.

When you first start uploading is really fast, however a few minutes into the upload it starts slowing down and down, and down . Where it may take almost all day to upload a 34mb File, to my web site.

Any ideas, or suggestions in how to increase the speed.
