Server Lag Issue

My server is too lag and i only host it here in my shop

SPECS

AMD ATHLON 3.0 GHZ
2 GB OF RAM
500 HD

And i use Auto Patch Launcher by Ianz , my CPU Usage is only 1.20 GB of Ram

maybe the connection that makes it lag

huh? connection? im hosting LAN only , so connection is not a problem , please PRO answer my question T_T

check your cpu usage (the processor)...how many percentage ? stable server is max cpu usage 75%

Its 100% but does it have to do with the lag? im just hosting LAN and my RAM usage is only 1.20gb and i have 2gb of ram

if you want to host with no lag ! upgrade your CPU or Buy a Highest CPU because your cpu is overflow ! its causes lag ! -_- !

i think your hosting a EP7 !??

How many cores do you have?

CPU usage 100%....absolutely make lag
I bet your Processor is 4 core.

For session, login server, field server, agent server . each need 1 core to be processed.

Buy CPU with 8 core
or
use 2 CPU each 4 core

It only have 2 cores, AMD Athlon is like Intel Dual Core.

i test my server for single core only with 2gb of memory, intel motherboard (Green) and more than 10 player can connect and speed is good Running in LAN also.

Thank you everybody for your help and feedbacks , i solved my problem and now my CPU usage is back at 62%
