One thing that may explain why there is no significant performance loss on the AMD PC is that the 980 Pro SSD is superfast, 10 times faster than the SSD on the laptop. Would running CPU-Z test on the Intel machines in both VirtualBox and Hyper-V make sense? And again, the same virtual machine works faster in Hyper-V on those two laptops. To install and setup the complete environment takes two days, that's why I am saving my time by moving the virtual machines between physical computers. I don't have a free week for this, sorry.

Dec 2012, 01:20 Location: Czech Republic Primary OS: MS Windows 10 VBox Version: PUEL Guest OSses: Windows 10 64-bit Is there any explanation why there is no significant performance difference on AMD PC, but it runs two times faster in Hyper-V on both Intel laptops? One thing i noticed the CPU clock speed reported in Task Manager in VirtualBox guests is lower than in host and Hyper-V guest. Intel Core i5 2540M, 8 GB RAM, Intel 535 SSD - double performance in Hyper-V compared to VirtualBox Intel Core i5-8265U, 8 GB RAM, WDC SN720 SSD - double performance in Hyper-V compared to VirtualBox Hyper-V was uninstalled and disabled for VirtualBox tests, of course.ĪMD Ryzen 5 3600, 32 GB RAM, Samsung SSD 980 Pro - no significant performance difference between VirtualBox and Hyper-V, approximately 5% slower in VirtualBox as expected No software was running on hosts, no 3rd party antivirus crap, Windows Defender disabled in guests. Laptops were always AC powered to get maximum performance. Performace tests were made by running unit tests (mostly CPU bound rather than I/O) in Visual Studio that takes several minutes. recommended settings of CPU and RAM in VirtualBox guests and then the same settings in Hyper-V.
I converted the VirtualBox VDI to VHD and tried in Hyper-V on several machines. I am aware that Hyper-V is a different kind of software, but this my finding are strange anyway. I use Windows 10 圆4 host and guest (MSDN) for development (Visual Studio, MS SQL Server and so on).
