TerraFirmaCraft requires a minimum of 1GB of memory to smoothly run single player without running into obvious issues. If you are using a 32-bit operating system, this is also essentially the maximum amount of memory you will be able to allocate as well. If you are using a 64-bit operating system, and are properly using a 64-bit version of java, you will be able to set your maximum higher. -Xms is used to set the minimum memory, and -Xmx is used to set the maximum memory allocation. -XX:NewSize and -XX:MaxNewSize should be set to 25% and 50% of -Xmx respectively.
