FPS starts to drop when I put a lot of tanks for liquid

[DanielRite]

With development in this mod comes the need to store large quantities of different liquids. For this I use cisterns, but with a large number of cisterns in one place fps starts to fall very badly, and I do not know what to do about it, maybe there is another way to store a large number of liquids? I apologise for my English, I write through a translator. I don't have a weak computer, and my friend has an even more powerful one, but we both have the problem
