Hello, I have a problem:
When mekanism is activated on my server, with a map containing some circuits, the CPU load reach 99% (only for the minecraft application)

additionaly, during the loading of the server, I have some messages like that:
[11:26:09] [Server thread/WARN] [FML/]: * **The modid Mekanism is not the same as it's lowercase version. Lowercasing will be enforced in 1.11** [11:26:09] [Server thread/WARN] [FML/]: * at net.minecraftforge.fml.common.FMLModContainer.sanityCheckModId(FMLModContainer.java:139) [11:26:09] [Server thread/WARN] [FML/]: * at net.minecraftforge.fml.common.FMLModContainer.<init>(FMLModContainer.java:124) [11:26:09] [Server thread/WARN] [FML/]: * at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) [11:26:09] [Server thread/WARN] [FML/]: * at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) [11:26:09] [Server thread/WARN] [FML/]: * at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) [11:26:09] [Server thread/WARN] [FML/]: * at java.lang.reflect.Constructor.newInstance(Constructor.java:423)...

do theses messages are normals ? Maybe it is the cause of the CPU load?

Why is my CPU overloaded ?

Now, it is so loaded than it is impossible to login on the server.

Full datalog of the server : log

Remove sponge and compare results without it.

I already tried. It reduce thé load of some percent (around 10%).
So i could play on the server. I walked all around the World where there are some Mekanism machin, i used them, and all was good; no problème.

Then, I added some pump, and à Solar évaporation plant. At this moment, the cpu load reached the 100%, and i am now unable to login on the server .

I also tried without Mekanism. The cpu load is around 8%
I tried a new World with Mekanism = 50%

1.11.2 should help fix this.
