First, why do you have plugins that do basically the same thing as each other? You have multiple plugins for generic commands, multiple plugins for chest logging, multiple memory monitoring plugins, etc.

Also, depending on your settings, LogBlock and DynMap can be resource hogs. I am sure a few others could be too that deal with similar things.

 

I'm going to say your outlandish java options don't help. They even include random /'s where there shouldn't be, and several miswritten.

try a simple -server -Xmx3G -Xincgc

 

sometimes the functions I need for some plugins doesn't work, like memory monitor has been modified to show how much schedulers are being scheduled etc. LogBlock also doesn't seem to log chests and CommandBook + Essentials as there are many commands I need in CommandBook not present in Essentials.

ah, I'm using rToolkit, made by it automatically and runs normally.

I followed this: http://forums.bukkit.org/threads/how-can-i-optimize-my-i7-24gb-dedicated-server.3967/

I also tried removing the extra parameters but it still ate CPU.

 

If your still struggling to find out the cause, try removing your plugins one by one to see which one Eats the most RAM/CPU up

 

well, I just used VisualVM yesterday, apparently the ones who used the most CPU (or take the longest time) is Orebfuscator, Ptweaks and Dynamic Map (A little of spout). I removed them and it seemed better. For RAM usage, I can't seem to find out what. But I think it's Minecraft Server itself. "byte[]" tables takes up the most RAM.

 

The byte[] arrays are the map chunks of minecraft, so that should be correct.

 

Yep blame Notch Hope Jeb can do better.

Also this could be because my server has a total has 7 different worlds loaded. 2 is EXTREMELY big.

 

Ptweaks itself only uses a little CPU but the end results are still better
