Thank you for your answer.
What arguments do you suggest have better GC?
I have used these one: https://aikar.co/2018/07/02/tu…ctor-flags-for-minecraft/
But they does seems optimized for modded minecraft 
I am running java 8 and have 16Go RAM on my VPS
Thank you for your answer,
Here is the output of the command "sampler memory --gc":
[07:47:07 INFO]: Heap: 412 / 1369 MB (max. 12884 MB).
[07:47:07 INFO]: Non heap: 190 / 196 MB (max. 0 MB).

Oh my RAM was 100% during startup now but it falls down to 2014M, thank you, is it due to the removal of this argument? Or to the sampler plugin? Or both?
Hello,
I am running IC2 on my server with few other mods. But I got a noticiable issue with it.
Actually when I run it on my 16Gb of RAM server, it put the RAM usage at the maximum I allowed for minecraft (12Go) even with no one online on the server it is all the time at 100%.
But when I remove the mod, the RAM usage come back to normal (around 2,5Gb with no one on the server).
I am running it on debian 9 using java 64 bits.
Here are my java arguments:
java -Xmx12G -XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:MaxGCPauseMillis=100 -XX:+DisableExplicitGC -XX:TargetSurvivorRatio=90 -XX:G1NewSizePercent=50 -XX:G1MaxNewSizePercent=80 -XX:G1MixedGCLiveThresholdPercent=35 -XX:+AlwaysPreTouch -XX:+ParallelRefProcEnabled -Dusing.aikars.flags=mcflags.emc.gs -jar Mohist.jar
I am using: Industrial-Craft-2-Mod-Experimental-1.12.2.jar
Here are the other mods installed in the server :
Armourers-Workshop-1.12.2-0.49.1.jar
