I have big CPU Usage ! With only 26 Players Online it is about 80% Where is the problem??? Someone know? CPU: 80% - 99% Linux 3.2.0-33-generic on x86_64 Processor information Intel(R) Xeon(R) CPU E5472 @ 3.00GHz, 8 cores RAM: 8GB
Hmm well with bukkit you can only run a server with one of those 8 cores *I never understood why people get a computer with more then 4 cores it's really freaking stupid a quad core is fine* so right now you have about a single core CPU at 3.0 GHZ witch is why it's making your CPU go nuts jesus you don't need more then 4 cores a 8 core is a waste of money you don't know anything about how minecraft runs heck even with optifine I'm pretty sure it only runs like a dual core and you can't run multi threaded like you can with minecraft optifine you should have gotten a single core, dual core, or quad core but that's what I think about 8 cores there useless and a waste of metal
Run script command line Code: java -Xmx8192M -Xms1024M -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalPacing -XX:ParallelGCThreads=1 -XX:+AggressiveOpts -jar craftbukkit.jar nogui PLUGINS: NoCheatPlus, WorldEdit, OPLock, DrugsFTW, Vault, ZavAutoMessager, ClearLag, PermissionsEx, AutoSaveWorld, TotalAntibot, LWC, WorldGuard, SimpleWarnings, Essentials, cTablist, AuthMe, EssentialsSpawn, EssentialsChat, IBan, Factions, CombatLog IF I SET IT TO 1 CORE , IT WILL CHANGE CPU USAGE?
Okay seriously I know Bukkit doesn't support offline mode but you don't have to post this stupid shit that doesn't have to do with the problem. Bukkit only utilizes one core. So overclock your CPU or buy one that has a high clock.
what is the reason of becoming so rude ? you where not a part of the tread nor was i speaking to you He has authme and iban which highly suggest that he runs an offline mode server, and he may not have known that we dont help offline modes
Not entirely true. While bukkit only uses one core, you can use the other 7 cores to perform garbage collection and other caching, thus freeing the main thread for more effective use. Java is capable of using all 8 effectively, even if bukkit only uses one core to run the actual program. You can specify these things in your startup script or even set them globally in the java environment itself. Not to mention, the internal structure of the processor he's using also uses dormant cores for heat dissipation as well, allowing for a higher overclock. I haven't looked into his chip specifically, but I know the I-series chips (which are based off the xeon technology) will automatically overclock on a hardware level when there are unused cores SPECIFICALLY BECAUSE they are able to use the dormant cores to move heat through the chip. Instead of pointing a finger at someone else with a claim that they don't know what they are talking about, consider that it is in fact you who does not know what he is talking about.
I'd recommend you either change -XXarallelGCThreads=1, to -XXarallelGCThreads=4 or remove that line. Also, ClearLag is known to cause lag. Also checking the delay between world saves of AutoSaveWorld may be a good idea, it may be saving way too often.
