Query: Key problem

I have an old Microsoft Natural Multimedia keyboard I'm very attached to. Sadly, my new computer does not have a PS2 port, so I bought this so I could still connect it.Big problem: It's slow. I set my keyboard delay to the smallest value possible, but it still doesn't work with this adapter. Press if you press and hold a key, it pauses, stutters, the goes. I'm going to have to replace this item as it does not let me scroll or navigate smoothly and quickly with my keyboard.
