When XoloX is happy busy with downloading, I can hardly browse the web at the same time. Usually it takes 2 or 3 minutes for the first text or images to show up in my browser. Even when there is no or hardly any traffic for XoloX! If I shutdown XoloX, the problem is completely gone.
I am using an async DSL (512/64Kbit) with XoloX upload limited to 3k.
