Performance issue in city

Hello. So the server offers a lot to do now for crims civilians and cops ems their is a fair amount of stuff for everyone too do. Was wondering if their was a way to fix the performance issue in City like legion all the head aches caused by the amount of imports being in the area or all the head popping in the city it really makes it hard to do your job as a cop or even as a criminal when your going through the city and randomly have head aches every few seconds or have a massive head pop when crossing legion square.
