Alright here is the thing guys. 1. I am running a server off my computer while playing. 2. The users on my server are having crashing errors, freezing, lag. Two of which are in the same house as me. 3. I am running my server off a .bat file with the command string as such : @Echo OFF SET BINDIR=%~dp0 CD /D "%BINDIR%" "%ProgramFiles(x86)%\Java\jre6\bin\java.exe" -Xincgc -Xmx1G -jar craftbukkit-0.0.1-SNAPSHOT.jar PAUSE 4. My system specs: Ram: 8gb DDR 3 Processor: AMD Phenom II X4 945 3.00 GHz ( Quad Core ) Hard Drive: 1 TB running at an unknown RPM ( Have not gotten around to checking it.) 5. I am running quite a few mods though the lag has always happened even before I switched to a bukkit server. Also, I am running off of hamachi My question: Who can I make it more smooth for the players on my server?
