    Default Problem CPU Usage of Java Platform SE binary

    Hello guys,

    My PC Specs : Intel i7 2600k - 8 cores, 12 GB ram , 1 SSD 120, 1TB HDD ( Java JDK x64)
    As OS : Linux x64/Windows 7, 2008 Server

    I have a little big problem with CPU Usage of Java Platform SE Binary.
    Actually I own an test l2j game server that create me problems.
    I don't understand the using of CPU when I start the Game Server java uses 0-1% CPU.
    With 1 player online the CPU Usage goes 30% but after he logout and I have 0 online the CPU maintain the 30% of usage.
    Searching over 2 months I didn't get yet an correctly answer.
    I don't understand where is the problem cause I ask a lot of people that have same server
    I change a lot of packs of servers/OS and still the problem.
    Some people have servers with 1000 players or more online and I'm thinking if I will open my server what will happen with 100 people online and the CPU usage if with 1 player its 30%.
    So please if you have an advice what I can do to fix this problem please don't hesitate to write me an answer.

    Thanks in advance

    What happens if two players connect?
    Get in the habit of using standard Java naming conventions!

    What kjkrum says.
    It is more than likely that that 30% is the basic server load, and additional players will make little additional claim on it.
    Please do not ask for code as refusal often offends.

    First of all thanks for answers.
    The CPU maintain the usage with 2 players like with 1 and when players log out same CPU usage.
    As I do a lot of tests seems to be a problem with the l2j game pack I use but I'm the only who have this problem I ask a lot of people that are using same server like me and didn't have this problem.
    I used other server pack for tests and I didn't have problems...I don't understand.
    I can't change the server pack cause I worked at it about 1 year thats why I need fix this problem.
    The CPU Usage happens same with the clean l2jpack (l2jfrozen) without any modifications or compiled java.
    Tests I have made for who know's the l2j game packs was L2J Frozen that have problems and L2J Acis that I don't have that problems.
    It's any way somehow to figure it out the exact problem of usage ? I don't know an program or something to coordonate me at the file of the java that use CPU. For moment I use Windows but problem is same on linux.

    Something inside that code is therefore starting up when a user connects and isn't stopping when they disconnect.
    I'm not sure what you expect us to say.
