Windows Strange Lag

[Milice]

Hello OTLander, today i need your help. My server lags (not much, but still annoying).
these are my computer specs ( the ones that matter )

AMD Phenom II 1055T ~ 6 Cores 2,8GHz
8GB DDR3 1066 MHz

I got more than 50% available ram, and my cpu usage is around 20 - 30%

i'm using Windows 7 Ultimate 64bit
and server is compiled in 64bit mode too..

Just - WTF is the problem?;o


~ EDIT ~

I can play online games such as League Of Legends just like normal with no lag and stuff even while the server is on, so its the server and not the computer.

And i know Linux is a good solution but i don't have an extra computer atm and i want to be able to use it as normal too

How many players are online at your server when it laggs? Is there anything people could abuse to make the server lagging?

 

[Milice]

Nope, nothing i can think of, and atm i got about 20 players online so its pretty strange :s

Got 11 atm and it uses 2GB Ram ;o

Maybe scripts?
Or any abusing bug?!
There's people who uses programs for lagging server too :S
^¿?
Have u any error in console?

 

[Milice]

Nope, no errors, and scripts im pretty sure are not lagging the server..
