Hi all, I wanted to know if it is normal that running a vanilla server use like 1% of my CPU and running CraftBukkit use 25% of my CPU even if there is nobody connected and no plugins installed ? Why CraftBukkit need to use so much Ghz when nothing happen on the sever ? cs:go or Bf3 servers don't use as much cpu. I have intel i7 850 with 12go of ram gskill. 1. What OS are you using ? win7 2. What architecture is the OS you are running ? x64 3. What version and architecture is your java install? 1.6.0_35 4. Are you running any wrappers? McMyAdmin, mcadmin, Hamachi, etc? no 5. What build of CraftBukkit are you running? i tried both 1.3.1-R2.0 and 1.3.2-R0.1 6. What command are you using to run your CraftBukkit server? javaw -Xmx1024M -Xms256M -jar H:\minecraft\craftbukkit.jar nogui 7. What plugins are you running? no plugin 8. What error are you getting (post your server.log file)? no error Ok i finally found why CraftBukkit take 25% on my CPU => it is because i started it with javaw.exe and not java.exe . javaw is something like the windowed version of java. When i launch vanilla with javaw the performance is the same then lauching it with java. I don't know why when i start craftbukkit.jar with javaw and not java there is a big CPU issue.

Try this command: java -Xmx1024M -Xincgc -jar H:\minecraft\craftbukkit.jar Note this is not javaw, but rather java. If you still see large CPU usage, try: java -Xmx1024M -Xincgc -jar H:\minecraft\craftbukkit.jar -nojline Also, I do hope that H: drive is a local drive, not a smb share.
