# 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.

#-Xmx18G
