Sorry if this has been asked before, I can't find the answer online. The "user_jvm_args.txt" explains how to do it somewhat, but I don't know where to put that line into. The txt file says this:
# Xmx and Xms set the maximum and minimum RAM usage, respectively.
# They can take any number, followed by an M or a G.
# M means Megabyte, G means Gigabyte.
# For example, to set the maximum to 3GB: -Xmx3G
# To set the minimum to 2.5GB: -Xms2500M
# A good default for a modded server is 4GB.
# Uncomment the next line to set it.
# -Xmx4G
Thanks!
Normally, I would just add the xml and xms into a jar file, but later versions of Forge don't have the jars.
