Firstly while I understand that the error is because WIndows is reporting 2 cores, I do not understand why what windows says is a reason to not fix it. Because other products such as cpu-z, vmware etc. are reporting correct number of cores.More virtual CPUs are assigned to the virtual machine than the number of physical CPUs on the host system (2). This is likely to degrade the performance of your virtual machine. Please consider reducing the number of virtual CPUs
The second problem is the bold part of the message which is grossly misleading. Because it actually improves performance greatly if I select 4 cores instead of 2.
Numbers don't lie, I ran tests using sysbench and stress-ng and for simplicity I am putting results from sysbench only but I attached the script I used and full outputs to the thread:
As you can clearly see, using 4 cores double the performance compared to 2 cores. The results are similar for stress-ng1 Core VM
1 thread 158s
2 thread 159s
4 thread 154s
2 Core VM
1 thread 155s
2 thread 61s
4 thread 60s
4 Core VM
1 thread 152s
2 thread 64s
4 thread 27s
This must be fixed, first VirtualBox detect wrong number of cores because it relies on Windows, secondly the message is misleading and causes people to have worse performance if they rely on VirtualBox recommendation.
Thanks,
