Hosting multiple servers on 1 pc?

So I looked online and couldn't really understand and really get the solid source answer for this concept.

Providing my VPS and withstand the processing power required for 2 servers, how can I go about hosting 2 servers at once?

/hosted different workshops
/different addons enabled (or does my addons have to be cross-compatible with darkrp & ttt)

Any info would be great. I'd be nice to be able to have more than just 1 server running and not have to buy a new vps or whatever else cases may be.

You just need to set one of the servers to a different port, thats all.

The port selection is entirely automated, you don't need to do something specific or idk what

Make sure the second server has a different port. Edit the start.bat file and put in -port (any number) and it should work.

use a host dont use your computor, alot easier to hack your intetrnet if you run it on your computor

Adding a port command didn't do anything.
Still interested in learning how to do this.

For windows a program called Nuestart works pretty well unsure if u can find it anymore makes setting affinities and threads easy, for linux even more simple as just adding a crontab and running the srcds from 2 individual crontab commands or alter linuxgsm, lots of very easy and obvious ways if u use linux specially limiting the threads, The game runs phenomenally well on a single thread i've ran 7 80 slot servers and webserver on a i7 2700k in the past.

Don't listen to guy who said hacking internet thing that's dumb. But yeah about the Ports and nuestart is pretty good.

Set random ports on both and set diff CPUs.
Example:
You have your RP running on CPU #1 with port 27019
And you have your TTT running on CPU #4 with port 1337
