I am working on setting up a Minecraft server on a machine I have at home. This particular machine has two quad-core CPUs running at 2.0Ghz so I would like to take advantage of the number of cores and run a server with 4 or 6 of the cores. My server of choice is CraftBukkit, the latest version of which is craftbukkit-1.4.7-R1.0 and launched with a start-up script of:
"C:\Program Files\Java\jre7\bin\java.exe" -Xms1G -Xmx8G -jar craftbukkit-1.4.7-R1.0.jar"
The Minecraft Wiki says:
Minecraft servers, as of 1.1.0, can use multiple cores, so now they will not sit idle.
but does not really expand on this.
My questions, then:
- Is it possible to set the number of cores the server uses?
- How do I do it - via start-up options, or other methods?
- Is it really worth it and would it make that much of a difference with a lot of players?
