I recently set up a csgo server on an old machine and it's working surprisingly well. I cleared out core 1 and dedicated it to only the server. I took a note of the var and sv when there are 1/12 players online:
- Players: 1/12
Core: 1
Then I started to stresstest cpu 0 (server is on core 1) and got these stats:
- Players: 1/12
Core: 1
As you can see my sv and var went down. I though it might be the cpu-frequency that was fluctuating so i forced it to 2.7GHz, but the results was the same.
The way i forced it to 2.7GHz was to disable the intel_pstate module and activate the acpi-cpufreq module.
The server is hosted on an old laptop:
- hp elitebook 2560p
Intel(R) Core(TM) i7-2620M CPU @ 2.70GHz
4GB 1333MHz DDR3 RAM
OS: Linux laptop 4.9.0-4-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.65-3+deb9u1 (2017-12-23) x86_64 GNU/Linux
I disabled Intel HT in the bios but i could not find any power settings.
The server will never have more than 12/12 players online and I'm pretty sure that it will handle that.
