I'm dealing with some technical optimization problems with my server and i have few questions.
Is this normal that my server's console says it uses 10.0 of CPU? Does it mean 10% or 100%?

How can i force server to use second core?

[Amroth]

status is broken, use top instead.
You cant force to use second core in linux, but in windows srcds can use all cores.

How can you actually use all cores in windows srcds?

Read the manual for taskset.

Windows user here, I don't think srcds can use ALL the cores. It might be able to use at most one other.

Its automatically use all cores, but you can set two or more core to one srcds process tho.. here the good article.

Taskset do not help, it stay mostly on only one core.

Taskset does exactly the same on Linux as "the good article" above does on Windows.

Technically yes but not functionally at all.

You can give two or more cores to srcds, but its stay on only one. For example you give core 1,2 to srcds, but its just will jump core to core. not just stay %50,%50.

But windows does it. Dont know if all windows version does it tho, back in time Ive used Windows server 2008 and had successfully multi-threaded srcds. One srcds use two cores equally.

[Potato Uno]

Source engine is single threaded (AND not thread-safe) so I still question your lacking statement that srcds is multithreaded.

[Neuro Toxin]

If you run one server and check task manager. You can clearly see srcds uses all cores at once with small usage on each core.

If you set affinty to one core. You can see much higher usage on the assigned core.

Edit: i will mention when all cores are in use the sv var is bouncing / much less stable. I persume it's all the cache swapping.
