[Major Erection]

So I've recently got a new dedicated server. The specs are :
Intel® Xeon® X3460 2.80GHz
4 Cores 8 Threads
8 GB RAM
120 GB SSD

This is the cheapest one they have.

So I can easily run more than 5 128-tick servers on this machine but there is one issue.

If the players in the servers are more than 20, the SV and choke skyrockets. So what I wanna know is the reason this is happening. I know for a fact that my server is capable of handling 5 16-slot 128-tick servers simultaneously.

I'm not that savvy when it comes to Cores and threads that kind of stuff.

Is there a reason why this is happening?
