Hi guys, I run my bukkit server, last stable build CraftBukkit: #766 Bukkit: #681 plugins: xAuth, WorldEdit, WorldGuard, LWC, Prermissions, PreciousStones, MyHome, AutoSave, Cookbook, CreativeBuild, EasyFlight, iOP, SimpleGive server: Core2Quad 2.33 Ghz, 8Gb RAM, Win 7 x64, Java JRE 1.6 x64 run with: -Xincgc -Xms1024M -Xmx1024M -Xincgc -Xms2G -Xmx4G when I connect to my server all are ok, but when any other player try to connect server cpu load up to 100% and server extremely lag any ideas what it can be? ps. of course I tried it without plugins, generated new world, used default server config , it doesn't help. I tried run minecraft_server without bukkit and it work well, so it bukkit problem Tried last build 798, work better, cpu load about 90% but can't test it alone, post result later ( EDIT by Moderator: merged posts, please use the edit button instead of double posting.
Dunno if this could help, but first I would allocate more RAM. Like -Xmx3G. or even 4, but actually I don't know how much java x64 can handle. My server machine (what's a very old one with 4Gb RAM and a x86 OS) could only use up to 1,5G for java / bukkit and that caused a lot of lag and the CPU load always went up to 100% (but went down after a minute or so).
Well, then you're using java x86. Remove everything java you have and install the x64 version. In your runningscript you have to put program files(x86) or smth right? you can remove the ( ) part then if you install java x64
I installed JRE 1.6 update 25 x64, and now tun server with this: "C:\Program Files\Java\jre6\bin\java.exe" -Xincgc -Xms2G -Xmx4G -jar craftbukkit-0.0.1-SNAPSHOT_798.jar But problem still Seems it something with chunk transfer from server to client, because chunks load very slowly... ps server has 20/10 mb/s internet link
Well, I dont use -Xms2G btw. Well you're using build 798? I would recommend to use a stable build. On my old machine the CPU load spiked up to 100% too, but not for too long.
all versions make my cpu spike to 100% when i join i have not tryed other ppl connecting but what the point of hosting a server if you cant play on it.
nothing change, cpu still 100% load after someone connected to server btw, one interesting thing, no matter who firstly connected, I or my friend, 100% cpu load for all connected players across first EDIT by Moderator: merged posts, please use the edit button instead of double posting.
