My server with BUKKIT always lags, but with official server does not.

Originally I'm using the official minecraft server to play with my friends.
Later we would like to add the "world edit" mod into the server and I(server op)tried to use bukkit.
As soon as I use BUKKIT, my server always lags(except me). I wondered that if it is my computer's problem at first but I found that my server runs smoothly when I was using the official server(all players no lag).

Is there any solution?

Win XP professional SP2 32bit
AMD phenom ii x4 960t BE(cracked to 6-core) , overclocked to 3.10GHZ
4GB ram
200M fiber network(with router, 25565port opened)

SORRY FOR BAD ENGLISH I'm from Hong Kong...........

 

Most probably your internet connection download speed/upload speed or there's not enguf ram. and what do you mean by official server.

 

When i use the official Multiplayer Server[see here: http://www.minecraft.net/download], there isn't lag for all players. But using BUKKIT, everyone lags. But we want to use mods=[

 

Is your upload speed 200MB/s? I highly doubt that. This is the reason that you are having problems. Your DOWNLOAD SPEED is at 200MB/s not your upload, go to speedtest.net and check to see what your upload speed is.

Do you run your server from a .BAT file? If not make one. open up a new document with notepad or notepad++, and copy/paste the following:

CD C:\Users\Dannyon\Desktop\krostcraft -- This is the location of the craftbukkit jar file
Java -Xincgc -Xmx2560M -jar "craftbukkit.jar" -- the -Xincgc -Xmx2560M shows that the

server will use as little RAM as it wants
while using up to 2560MB of ram at the
most,(2.56GB of ram). You can edit the
Xmx value to whatever you want but be

sure that is looks like this when you finish:

-Xmx(amount of RAM to use)M for megabyte and G for gigabyte


This is for Windows7 computer if you use a MAC I'm afraid I can't help you.

Let me know if my comment helped you. Or if you need more help of this topic.

Try using no lagg plugin and post ur results.

 

No, these plugins that say they can remove lag actually increase the lag.

 

no you cannot use mods in bukkit spout can so such things and did you mean plugins?
