Its odd, but the day I upgraded my PC, items moved in half the time from my inventory to the trade window and to retainers.
Yup, I also upgraded PC and trading items got faster. If I'm in a zone with few people my trading is instant. There is still room for improvement though. And with action lag. If your experiencing long delay between when you press it and when it starts try lowering graphic settings a bit. 1 second is normal, 3 seconds is not.
