    So i have lots of lag on my server :( but people can chat with no lag at all but when anyone enters a command nothing happens. Only after a few seconds or even minutes all the commands that the person entered will happen or everyone will get the internal exception read time out error. e.g if the person typed /home only after a few seconds the person would be teleported to their home.
    Please help!
    Btw i have 5500mb ram and currently its using about 75%

    It's using 75% of 5.5GB of RAM?
    That's not normal.
    Are you hosted with a company?

    almazio1 That does sounds like something is very wrong. But i still need a startup log to see if anything is abnormal.

    OK it's downloading

    Here's the startup log: http://pastebin.com/w0CHbLig but It's like 20 days old :( sorry the download just took 4 hours and it's 1000mb so i had to stop it :/
    BTW i removed The Infected and parkour plugin.

    Id need the latest startup log, try move out or delete the server.log, then start and stop server to get a small server.log with latest startup.

    You should totally get ClearLagg! It prevent's lots of lag and I have been using it for a little less than a year. There is no way to explain it! There is a easy to edit config and there are lots of options you can choose. Just click on the link and you be lead to it. Also if you have a custom world, or a big world it will take up lots of ram. http://dev.bukkit.org/bukkit-plugins/clearlagg/

    almazio1 Your startup time is massive. It seems that something is slowing down the server a lot, possibly a world?

    I noticed that Disguisecraft and Multiverse takes about 5 minutes each to start up. Other plugins start quicker.

    Btw when the server starts it's using about 50% ram but about an hour later it's using a full 100% even if the players leave it's using 100% and here is an error i noticed in my console: http://pastebin.com/NsL2Shu7

    I have also noticed that when the lag starts the cpu usage drops to 0%

    almazio1 Looks like world corruption to me. Try starting the server with fresh worlds and see what happens.

    Edit: derp

    Misread error, its actually a missing worldguard file.. though id still suggest trying with fresh worlds and no old ones.

    and my console spams this error:
    11:20:20 CONSOLE: [INFO] Read timed out
    Please help

    I have also been thinking to run my server of an SSD. Will that help?

    And I have about 7000 chunks loaded in my plotworld. Is that too much?

    hmm whenever i disable ptweaks some chunks start to unload, now there are just 1000 chunks in plotworld loaded...

    What I would personally do is backup the WHOLE server directory and make a new server and slowly copy everything over.

    That would personally be a ton of work though.
