I advise if possible choose a Xeon processor are higher quality and greater stability than an i7 or other processor and at least 8-core processor.

• 1000fps @ hlds = 1ms, Server Response (excellent)
• 300fps @ hlds = 3ms, server response (normal)
• 100fps @ hlds = 10ms, Server Response (bad)

The response time is in addition to your ping, affecting registration and accuracy of the bullets, the higher the better but more CPU consuming.

Do you know a good tutorial for beginners to install kernel lowlatency ?

I use this (Ubuntu):

Best tutorial about Kernel build (I use translated, Russian version for me).
(you should use "make menuconfig" as configuration method)

I have a low-cost virtual server and I first had Ubuntu on it. Recently swapped to Debian since the memory usage is much lower (I don't need the Ubuntu stuff on a simple server). It's a 1-core 2,66ghz with 512MB ram. I was testing if I could run a 1000fps hlds (DOD 1.3) on it, but I only got about 500-700. After a couple of matches I thought the hit reg wasn't so good.

What I did to achieve low latency kernel was this:

First I upgraded the kernel to a RT version, which has PREEMPT already configured (you want this with 1000hz):
https://wiki.debian.org/HowToUpgradeKernel

For me the search found this:
linux-image-3.2.0-4-rt-amd64 - Linux 3.2 for 64-bit PCs, PREEMPT_RT

After installing and booting to the new kernel, I downloaded source and compiled it:
http://kernel-handbook.alioth.debian...mon-tasks.html (Part 4.5)

At 'make menuconfig', just exit it immediately and it should generate a file '.config'. Edit it and look for these lines and change them like this:

# CONFIG_HZ_100 is not set
# CONFIG_HZ_250 is not set
# CONFIG_HZ_300 is not set
CONFIG_HZ_1000=y
CONFIG_HZ=1000

Save it and follow the rest of the instructions. After successfully booting to the new kernel, you can check the current config:

cat /boot/config-$(uname -r) | grep HZ

This didn't help me to get 1000fps since the server is too poor, but I made it run with ticrate and fps as 500. Now the hit reg is awesome compared to servers we usually use on this scene.

Hello,

its me again after couple months.
I have still not found the right solution.

Finally,which OS is better: ( according to your experience )

- Ubuntu server 12.04 lts + kernel lowlatency
- Debian nad RT kernel version
