Server performance

    I got a little Bukkit Server on a localhost here (4GB RAM, intel8500 DualCore CPU and a HDD). I use bukkit 1.2.5-R4.0 and Worldedit and Commandbook 2.0 and the performance of my server is horrible and I think its getting worse.

    Last time, cutting 100k blocks made it crash, now i wanted to create a cyl with 14k blocks, crash again... i tried Java 6 and 7, even the newest bukkit version... no improvements. I think its software based. Sometimes my CPU goes to 100%, but why a crash? I have time, let it render 30 secs... fuck the crashing!


    2012-06-24 19:14:29 [WARNING] Can't keep up! Did the system time change, or is the server overloaded?
    2012-06-24 19:15:41 [INFO] XYZ lost connection: disconnect.endOfStream
    This sucks :( I tried to give more RAM to the Server (btw why must i do this manually? server, take what is available!) Any ideas? I am not thinking about investing 400€ just for a little MC...

    Thank you.

    Are you running a 32 or 64bit OS?
    If you are running a 64bit OS, make sure you use jre7 x64 for better performance (don't put 'java' in your start.bat, but set the whole path to java.exe)

    Install nolagg plugin , it helps to reduce system usage a bit.
    Bukkit only uses one core of your CPU. what HDD do you use? (speed)
    try reducing view distance?

    changing 100k blocks can be intensive. Even for me it takes sometimes more then 5 seconds (I7-2600 @4.5Ghz) so I would recommend changing smaller parts?

    I tried 32x java 6 and 64x java 7... no effects. Nolagg sounds like a help, will try that. Thanks. My HD is a normal Caviar Black with 7200rpm. View distance... is an option, but not a good one XD

    And yeah, thats the only solution til now... smaller parts.

    Over the life of Bukkit and World-edit, performance has definitely gotten worse. I remember when I could cut 6 million blocks without a crash in 1.7.3 and now I'm lucky to cut maybe half a million without a crash. Also after owning a server for quite a while and using World-edit for even longer it has always seemed to me that some blocks are more CPU intensive then others. What blocks were you world editing?
