CPU benchmark, how to know that we have not been deceived?

Question

Network administration

The essence of the question is as follows: For example, there is VDS/VPS hosting.
I don’t think that everyone is directly burning with the desire to be “swindled” on resources and stumble upon an “oversell”.
How to test and find out what is really allocated, for example, 3GHz and, say, 4 cores?

Answer 1

In general, no way. First of all, read what kind of gigahertz is in the agreement, maybe everything will be cleared up there. Well, after - cat /proc/cpuinfo, ideally there should be 4 cores. We also run some useless synthetics, on the standard and on the virtual machine. Ideally, the virtual machine will be weaker by 2 times, no more. A virtual machine is ideal when fast scaling is required and / or the resources required are negligible. Otherwise, you would need a dedicated rack ...

Answer 2

no way
now I can show you 4 cores of 3 gigahertz and tomorrow I can deceive you
myself I sell highly loaded hosting for a high price so I can not deceive my customers
