I am having problems with intensive CPU usage and RAM usage. Specs: Core i7 2600k 16GB RAM CentOS 5.5 64bit (running as a dom0 xen master machine, so it's not a VPS) java latest version (updated few days ago, can't remember the version) Craftbukkit #953 (also happens with newer/older builds, stared happening a while back, can't exaclty point out when) 55 Slots Plugins: WorldEdit/WorlgGuard/mcMMO/a lot others Problem: CPU usage gets as high as 200% (don't ask me how that's possible) after a few hours of server uptime. When the server starts, the cpu usage is at 40-70%). The server has 10 GB of RAM allocated to it, at start only ~1gb of ram is used but after a few hours it can go up to 7GB of RAM used. I'm measuring the CPU usage with top and the RAM usage with CommandBook's /debug info. Is there a way to make Minecraft multi-threaded (support more than one core) ? Thanks!
