    Hey !

    I'm having a bit of trouble at the moment, my TPS is never really constant. It can stay at 20 for a while, and all is good, but then it'll drop, dramatically...

    The problem is, the server seems to be running really high on CPU, and barely any RAM is being used compared to what it has to offer.

    I just don't feel I should be using anywhere near this amount of CPU with the little amount of players are online. That and the TPS being that low is just ridiculous...

    Any ideas ? :/

    Thanks !

    That's a ton of plugins, might be that? Try removing some that you dont "need"

    Try enabling plugin-profiling and check which plugin takes a lot of time processing stuff.

    I was having the same problem. Once I removed PlayerHeads it was fixed.

    RetroCola I need most of them. I've removed a few, but a lot of them I need. Still, I've got a powerful server, none of these plugins *should* be massive power hogs. :/

    Shouldn't think it's that much, is it ?

    Lolmewn I've got it enabled. What plugin can check to see which plugin is using all the cpu ?

    rguz10 Removed it, hasn't helped. :(

    TPS is currently at 4.3, 10 players online :/

    Pr4w If you have it enabled, do /profile merged (I think that's the command, can't remember. It's default from Bukkit anyway)

    Pr4w Looks like the plugin 'Tutorial' is messing a lot with CPU and shizzle. Might want to update that.

    Tutorial's the name of a map, why would it cause these kinds of problems ?
    It's got a fair amount of redstone in it, but not that excessive. It's a creative map for tests and such

    Unloaded world, TPS went from 4.7 to 20 within seconds, unbelievable :confused:

    I'm assuming redstone is the problem. But how can I determine exactly how this world is causing lag ? And what can I do to prevent this ?
