Get SEToolbox, download the save and open it up. Consider a limit on the number allowed per ship/station, as 20 turrets on a large ship constantly hunting for targets will hurt your performance. Turrets are another major cause of lag.

There's no need to have automatic configurable LCDs updating 50 panels every second on a large station or ship, when every 3-5 seconds will do. Ask that scripts on timers be set to run as infrequently as possible.Get a drill mod that lets you do more with one drill. The ships with 50 drills might look epic, they will negatively affect your sim speed. Set a limit on drills per ship if you have to.Mining has historically been the main source of slowdown in sim speed, which is why the voxel updates are so slow (far apart) when mining now. Ban auto miners (ships that use scripts and autopilot to mine).

There are many things that affect sim speed.
