One of the problems too with the amount of windmills. A lot of people don't know how to use power effectively and split their power with splitters and waste a lot of power when they should be using branches to branch out the needed power instead of using splitters. Splitters have their use when you need to split power equality to 2 or 3 parts. Like if you were powering 3 doors, branch out the power to a splitter that splits to the 3 doors. But people are using splitters and waster 30 power here and there. So they just spam more windmills to try and solve their power problems.
Removing splitters until you follow a guide and pass an exam on how to use them properly would be nice. Also people who do farms and just spam Sprinklers and lights. You only need 2 sprinklers and 2 lights for 6 planters. 2X3. But because people don't know how the water divides and is calculated. They also spam sprinklers. That is why the huge farms cause lag on the server. Because people just spam as they don't know how to be efficient, and it just multiplies this problem as they move up and expand said farm.
Another issue, there should be a limit on how many composters one can deploy. How many TC one can deploy, add decay, reduce the stack size in TC. So things would decay naturally. And reduce lag
