Most of the aircraft if 'left alone' with regards to speed, slow down to about 160 at 10DME, except VLM with their Fokkers that can do 224kts until 7DME then feather the props & snap the necks of the poor pax in the back as they pull about 6negG's!
The fastest ive seen is a Shell Falcon with a Ground speed of 380 with 12 miles to go. The highest approach was an EAE Atr42 drop from 3000' at 4 miles with overcast cloud at 800' - and according to the tower popped out of the cloud in significantly nose down profile but flared and made the best landing that controller had ever seen!
Oh for a camera!
