How to check if the CPU on VPS is dedicated or shared?

Is there a method to find out?

Thanks,

  • even the name proves it if its vds or dedicated server then it means its dedicated or else in case of vps it means its shared.

  • from the vps plan name

    Thanks! Yes, the naming actually makes sense. I was looking at HostHatch's 'Black Friday 2023 - AMD Compute 8 GB - T1' offer. It comes with 4 cores, but I don’t recall if it had one dedicated core and three shared, or if all four were shared.

  • they are always shared and if its priced 0.50$ its overcommitted too

  • Mine crypto for a week and if it’s not suspended, CPU must be dedicated.

  • Judging by the price.

    Hammer it 24x7.
    If it's dedicated the provider will not suspend you.
    Otherwise they will suspend it or terminate your account.

    What are you trying to ask here? How will the outsiders know about anything? Create a ticket with thr provider and ask them directly.

    If you know the exact service name I can search it from the pony cache. However Black Friday 2023 - AMD Compute 8 GB - T1 returns no results.

  • Have you tried to Google?

    Hi,

    1. check the CPU Model
    2. Check online 1-3 benchmark results for those CPU Model
    3. Run occasionally this 1-3 benchmarks on your server
    4. compare the online results with your results

    Make sure to math out your own usage ( or stop your usage during testing ).

    Your results and the results of the online database for the specific benchmark should in average not be much more away from each other than 5%

    If they are in average (far) away from each other, then you know that you have obviously less CPU at your service than it should have.

  • Usually you'll pay a premium and they'll mark it specifically as a VDS and not a VPS.

    If you aren't sure, assume it's shared. If you want to know, submit a ticket and ask.

  • zoxzox Member

    Contact support, and ask if there is a fair usage policy for your vCPU ?
    Thats what I aways did, If I had doubt.

    4 CPU cores (100% dedicated, burstable up to 400%)
    8 GB RAM
    100 GB NVMe storage
    10 TB bandwidth
    $55 per year
    (1.5X RAM, storage, and double bandwidth for 3 year payments)
    

    So you can max out 1 vCPU if you like.

    EDIT: oh, I see I was late to the replies. BTW - one thing I always do is that I have a spreadsheet where I record all my servers and one of the columns is a link to the offer thread if that's where I got it from (I almost always do get them via a promotion).

    Thanked by 1cainyxues
  • There is no way to tell for sure. However, if your plan comes with more than 1 core of CPU per 4GB RAM, then most likely it is a shared CPU, not dedicated.

    For example, 6 core CPU with 8 GB RAM --> 99% chance shared CPU.
    1 core CPU with 8 GB RAM --> probably dedicated CPU.

  • Thank you! I actually opened a ticket earlier today about this, and HH confirmed that it's 1 dedicated core and 3 shared. It's a very good deal, actually. I'm shuffling my servers around and couldn't remember.

    The reason I asked here was to see if there’s a technical way to figure this out, but it seems there isn’t.

    Yeah, it's a great idea, actually. Keeping a spreadsheet with all these details is very helpful for when you need it.

    Everything's sorted now, though. Thanks!

  • If you are expecting dedicated per the plan, load them for more than 10 minutes and you are fine. Likely to see service ban or hold after 10 min if shared.

  • I looked at the answers and was amazed by ppl pointing out VPS and VDS, but the real question is how you dedicated a core in virtual machine software or assign a shared core to a vm?

    4 CPU cores (100% dedicated, burstable up to 400%)
    

    Hmm .. I'd take that to mean that my "cores" actually are but 1/4 of a HW thread and not dedicated.

    We use the same terminology that Linux does. 100% = 1 core. We no longer do this in our newer advertisements though, or on our website.

    Providers can bind vCPUs to a specific physical core using CPU pinning or affinity settings in the hypervisor software (like KVM/VMware/Xen).

    I was pondering the other day, because I don't know how steal, is actually measured, but I was trying to work out if locking a VM to "dedicated" 25% of a host core would show up as steal because as far as the guest VM was concerned that's exactly what it is - even if the underlying host isn't heavily loaded at all, the guest would still be seeing periods when it detected its virtual CPU didn't make progress. I'd guess it's based on RDTSC somehow.

    They can, but that often results in threads, not cores (HyperThreading/SMT).

    In a system with a dedicated core, I expect to see two CPUs in the OS..

    Here are some tests to inspect whether your CPU is shared or dedicated:

    • Provider's Website: Shared CPU is mentioned as vCPU, and Dedicated will be Labeled as Dedicated CPU.

    • Steal Time (type top or htop in CLI): High % value (>10%) for shared CPU and Close to 0% for dedicated CPU.

    • CPU Shares (cpu.shares): 1024 or lower for Shared and 2048 or higher for Dedicated CPU.
