Unity applications using balanced CPU!?

I have 5 servers have to run in my vps.

But when I run them all, they are using %20 CPU total (like %5,%5,%6,%2,%2).
If I run only one, %20 again but its enough for one server.

So when I run them all, there is a lag start because the server can’t use the enough cpu.

How can i fix it?

This is the solution, thank you really.
I give one program to one core. now all %20-%30 and no lag :slight_smile:
