I have been building a large ship with many large rail docked entities and even though I had 4 times the mass limit of the turret in mass enhancers it was still taking around 10 minutes to rotate 180 degrees. There is at that point a pile of single rail basic docked entities which don't move but combined mass would have been close to 150k mass. So I assume that even though this is stationary that its some how applying to the turret rotation speed or its bugged somehow. Though the smaller mass doors slide open and close just fine.
I got around this so the 6k mass turret rotates very quick
Vertical rotation turret part
Horizontal rotation turret part
Fixed Base
Main ship hull
This has fixed this turret rotation not sure what impact it has on the other main ship mounted railed entities speed though.
