RAM: 128 GB DDR5 ECC 4200 mhz
Disk: 9.60 TB NVMe gen 4 nvme pcie

    Depending on use case

    Your can experiment and see what the usage is going to be.

    Top notch is subjective.
    Does it mean there is cpu steal?
    Are your customers going to be OK with slower than advertised cpu?

  • is the performance of general purpose 5 usd vcpu ios it ok to get 3vcpu per one dedicated thread?

  • It depends what's the usage of customer vm.

    You want to strike a good balance and monitoring to ensure threads do not get abused if shared.

    I feel you are trying to get the optimal number first before diving in, but sometimes it's OK to start with a guesstimate and fine tune it in future.

    Let customers know ahead of time that the cpu policies may change and are not written in stone.

    If you are offering shared cores make sure you are able to find out abusers (there will always be one and more) and take action

    Plus you can start conservative by keeping some threads free and offer only a few to users and check how that works

    Good luck

  • the server is cost a lot cus its latest tech and high frequency and ram etc thats why i want to seeif the total vms can payoff the server and make some revenu thats why and i want to give good experience

    You need to do some math to find that out. No one can tell you a definitive answer to the question because of all the factors involved.

    Only you know those factors we never possibly could even guess because it is your setup not ours.

    We could debate theories on this subject all day and night and you still will not an answer.

    The bottom neck likely be the memory than CPU itself. Remote server softwares that are high CPU intensive tend to be high on memory usage, you likely run out of memory first before running out of CPU.
