This greatly decreases server lag when e.g. someone makes a lavacooling mountain.
Sometimes I can see such a mountain created with lavacooling on a server, often it's made by me but not every time.
I have much more pictures, tell me if you want to see them, some of the mountains are much bigger.

I changed the code of my lavacooling mod that creating such a mountain with a lava and water bucket (or something else with lava and water) doesn't cause a server lag that it needs to become shut down because it's fairly impossible to continue playing there without disabling lavacooling (except on fast computers).
After that l changed the lavacooling of default in my version of minetest_game. Calinou's carbone game uses the code.
