Kernel optimization

[Andrej Parovel]

Hello,

I hear about Linux kernel patching and optimization for better running 
multiple game servers. I was looking around the net and find these 
article http://wiki.fragaholics.de/index.php/EN:Linux_Kernel_Optimization
I am a bit skeptic about these, because I also heared that 1000 HZ 
kernel can cause big CPU loads also when CPU is on idle without any 
running process. It is these true or with these guid and wiki the won't 
happen?
Also, is these optimization only for Counter strike games good? Will 
also Call of Duty games run better with these optimization or just, it 
won't get any worsest with it?

I am running different games on same machine. I am mixing on same server 
Counter strike and also Call of Duty games (and some other, but rarly). 
You think will these cause some problems or issues with such kernel 
optimization?
So pleas If anyone can advice me if it is good to do that? I think for 
Counter strike games have to be these done because of FPS drops. But the 
biggest problem I am thinking about if will such kernel efect something 
on my Call of Duty servers.

1000 HZ kernel might be a problem?

Thank you!.
