Im using a linux computer to host my minecraft server using this to start it up " java -Xms1024M -Xmx1024M -jar craftbukkit.jar nogui". It still gets a little laggy and i gets a spam of "cant keep up"s, it shows there is extra ram so what script do i use to make the computer run at maximum?
Change the '-Xmx1024M' value, if you wanted to allocate 2 gigs of ram you'd use '-Xmx2048M', and etc.
can't keep up messages aren't always about having enough ram. most people ignore them or get obuJustShutTheHellUp
