My cpu has 6 gigs of ram. But whenever I try to bring my ram up, it does not work. Echo OFF SET BINDIR=%~dp0 CD /D "%BINDIR%" "%ProgramFiles(x86)%\Java\jre7\bin\java.exe" -Xmx1500M -Xms1024M -jar craftbukkit.jar PAUSE That is my current BAT code. Please, my server lags a lot, and I am using almost none of my ram while having 3 people on it and playing. So I would like to fix that.
