you left out a verb there. severely what?
anyway, yes, i'm quite well informed on how the vps business works, because i used to run a company that sold vps. you have to oversubscribe to be competitive, otherwise you would be charging several hundred dollars a month per vm.
"it works perfectly" because of things like preemptive scheduling and fast context switching. but you'll never get the full performance of even one core out of that cpu unless all the other vms are idle.
you are also probably severely overestimating the amount of resources you're actually using on the vps. whatever you're doing probably could just as well be hosted on your laptop.
