    Poor performance on linux host, how to increase priority?

    zuber1979 Lurker

      I have VMWare Workstation Pro 15.5.1 build-15018445 running on linux Ubuntu host.

       

      I run Windows 7 x64 as a guest system.

       

      My PC is quite powerful - 2x Xeon 32 core CPUs, 64 GB RAM

       

      But virtual windows is running very slow.

       

      Is there a was to increase virtual machine priority? Or set affinity to specific cores only?

          VM specification? Storage type?

            2x CPU with 2 threads

            8 GB RAM

             

            I'm using real windows partition (raw disk) - not an disk image.
