Gmod dedicated server only using first core


I am having a small problem with my gmod server. It only seems to use one of the cores, however I have 2 on my server.

Htop shows 100% use on core 1 and 6% use of core 2.

How can I fix this?

Gmod can only utilize a single core and there’s nothin you can do about it.
