Hi, im new making servers, i made one to play with my sisters so, i dont know how to put more memory on my server because i think is runnning with 3gb and i want to put at least 12gb because i put alot mods, i have 32gb ram but i dont know how to do it, this file i dont know what to put in it:

@echo off
REM Forge requires a configured set of both JVM and program arguments.
REM Add custom JVM arguments to the user_jvm_args.txt
REM Add custom program arguments {such as nogui} to this file in the next line before the %* or
REM  pass them to this script directly
java @user_jvm_args.txt @libraries/net/minecraftforge/forge/1.19-41.1.0/win_args.txt %*
pause
 

if someone can help me with this please

You need to add:

-Xmx<size>

to the user_jvm_args.txt file, replace the size with the memory value you want
if you want to use 12GM the argument should look like this:

-Xmx12g
