CentOS 5.6 x64 Sun Java JDK 1.7 RemoteToolkit (if that counts) Build 1000 Several around the forums + Bare minimum (Xms and Xmx) Tried None and combinations of these: WorldGuard, WorldEdit, WorldBorders, Spout, SimpleReserve, OreObfuscation, Permissions 3.?, NoCheat, MultiVerse, MobDisguise, McMMO, MCBans, MagicSpells, LWC, LogBlock (and Questioner), Inception, iConomy, iChat-p3, FalseBook, CommandBook, CombatTag, Citizens, BlockHat, AdminMode Errors: None Tried: Disabling mobs (Doesn't do much) Several different startup settings (Doesn't seem to do much) Using Default startup settings (Xms and Xmx) (Seems to be the worst for CPU usage) Removing all plugins (Idles around 10-20% with just me online, Increases to 50-75% for 1-2 minutes after joining) Doing all of the above at the same time 10. Tried everything on that list I run a 15 slot bukkit server on CentOS 5.6 VPS. I am having issues with CPU usage and Memory Usage. Server Specs: 2GB Memory 2.5 GHz CPU 15 Slots ~7 Online on average My server's CPU hovers around 50-60% usage when there are 4-6 players online. I have noticed that my memory usage increases as the day progresses and gets to about 74% (out of 1.75GB) usage by the 6 hour auto restart. Even doing all of the above doesn't seem to help this issue. I have tried copying the entire server folder (except for the maps) to a VirtualPC on my computer (i7 3GHz, 3GB dedicated to the server) and it still seems to use a lot of CPU even when only one person is online. I guess the final questions are: Is this something that happens to be wrong with bukkit at this time? Or is it something I may be doing wrong? (I consider myself a novice when it comes to server hosting) Is there anything that can be tested or fixed in my case?
