Gmod Server CPU Usage

Ive noticed that gmod’s server software runs primarily off 1 cpu core, and bounces around from core to core. Is there a setting or launch parameter to get the server to utilize the processor more efficiently?

Gmod uses one core for networking and one core for everything else, you can not make it user more than that.

Can’t be achieved at all, that’s why it’s best to buy a Server with just One Core at around 4.2 Ghz or above for the best performance.
