Hello! I am developing a high performance server, and I have question about the usage of ramdisks.

I use a ramdisk, however, I like to keep it as small as possible. What should be kept in a ramdisk?

For Sure the World Folder and Logfile, but what else? I care only about operational performance, not about boot-time or anything. Is there a benefit to Ram-disking the plugins, mods, servers, and libraries? doesn't java load all this at load time anyways? What about configs? are they loaded once, or as needed?

 

Is there a way I can experiment with this? Is their some kind disk-io profiler for java? Can I run any kind of benchmark with and without ramdisk?

 

thanks!

~Tim

For stability reasons I advise NOT using ramdisk. But if you must, the only real concern is the world file.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

      Recently made a mod in Intellij for Forge 1.20.1 with everything seemingly working perfectly fine with 0 errors in Intellij although when I try to run it in-game the game crashes on startup and gives the error and now Im just confused as to what is causing this error.  The game crashed: initializing game Error: java.lang.RuntimeException: null Here is the full crash log: (excluding system details) ---- Minecraft Crash Report ---- // I let you down.
