Using a RAM disk can provide a great performance boost for programs with high disk activity, like database applications, compilers and even web browsers. You can use the RAM disk as a temporary storage container (any files will be wiped out after reboot) or mount it as a permanent drive that will maintain the content across reboot. The difference is that the read and write speeds are more than 10 times faster than with your regular hard drive. Once the RAM disk is mounted, it looks and behaves exactly like a regular drive. INVOCATION="java -Xmx$/logs/latest.RAMDisk enables you to create a fast performing RAM drive that runs entirely in your system memory. # Description: Starts the minecraft server via ramdisk # Short-Description: Minecraft RAMDISK Server If you don't, make a new text file, call it minecraft, and copy this script into it. If you have /etc/init.d/minecraft, delete it or overwrite it with this script. Again, this is a modified version of the script found at Aimless Bits. It's now a matter of simply running a modified script that loads the files on the drive onto the server, copies them back on a timely basis to prevent data loss, and does backups. Mount -t tmpfs none /home/username/minecraft_ramdisk -o size=512m The ramdisk will now be loaded every time you restart. Make sure that you give yourself some overhead. The size of the ramdisk MUST be larger than the minecraft directory world. Tmpfs /home/username/minecraft_ramdisk tmpfs defaults,size=512m 0 0 Then add this line, making sure that the path is correct (username, dir name etc.) To mount it as a ramdisk, simply edit your /etc/fstab/ file:.Firstly, start by creating a directory for the ramdisk in your home directory, i.e.It also helps to be familiar with the /etc/init.d/minecraft startup script. This quick guide assumes you have a user for loading minecraft, a minecraft directory and a server running. This guide fleshes out the process and makes some minor changes to Aimless Bits' script. It involves modifying the server startup script available on the wiki and making some minor changes to fstab. Make sure to back up your files before starting! GNU/Linux (Easy Way) Ī simple way to load a minecraft server into a ramdisk was posted on the Aimless Bits blog on March 12, 2011. Since a Minecraft world currently consists of very many chunk files, seek time is equally, if not more, important for overall speed. By moving the data into the RAM, access times will be near instant and data transfer rates will be significantly faster, making chunk loading and saving much faster operations. In a Minecraft server, one of the strongest bottlenecks are disk I/O related operations (e.g. Why it makes sense for Minecraft servers Unfeasible if the world size exceeds the available RAM.Ramdisks will be cleared when a system restarts (Not true for Dataram RAMDisk).
