need help understanding something with my srcds.exe process

Ok so I am aware that the server is single threaded, however I had my server running and the resource monitor open and it says that there are more threads then just one. Is this a error with the server? I know it isn’t the OS I’m running a fresh install. Could someone please tell me what I am seeing here.

It uses one thread for the server it’s self. while it will use a 2nd if it can, to handle networking. So at most it will use 2. So if you have one hyper threaded core, then that will be great for it.

actually it says 17 threads for me and when I load bots it goes to 19. I don’t think its correct but I’d still like to know whats causing it to say this. my first thought was addons but it did the same with and without addons.
