Ramshack
My extensive playing with multicraft and some other has led me to a MC Ram Hack for MC Servers. Buy the 256 MB pack, and then run an 8gb server. This has been tested on Multicraft, but I've heard it works on it all.
How does it work?
This program installs itself as an intermediary between the minecraft server jar, and the console. From there, it spawns a subprocess with ram specified in the mca.conf in your main directory.
Installation:
1. Install the Ramhack.jar into your main directory.
2. Run the file to generate the config file, or create mca.conf, with the following contents:
Code:
jar=minecraft_server.jar
ram=8192
slots=1000
With jar being your server jar name, and ram being the MB of ram to allocate. This works with any minecraft jar(or other game too, such as starmade perhaps).
3. Boot that jar as a custom jar, success!
*if your server does not start try this slots>=-1
Unlimited Ram
