Spaecraft Helm input lag

[Rockinsince87]

I've noticed it's not just input lag. There seems to be lag regarding ship acceleration as well. 

I've noticed this behavior whether I was piloting or not. What first tipped me off was when I ordered my crew to orbit a planet across the system. The ship came in way to fast that they had to circle around like crazy. So I took the helm and manually tried to stop the ship. That's when I noticed the deacceleration was way way to slow. I was only going 13000 m/s. It took me 5 minutes to stop. 

Using a ship with gravity drive 250 m/s.


I did quite a few test accelerations from 0 to 1000.
Only a few times did the ship actually reach this speed in 4 seconds as expected.

In some of the tests it took as much as 47 seconds to reach this speed!
