Windows 10: Hyper-V performance

Hi!

I have a c++ application that calculates 100 factorial a million times. I ran it on windows host machine and it took a few milliseconds to get processed but if I run it on Oracle linux 7.3 Guest machine created through Hyper-V, it takes 40 seconds.


Host machine:

total cores: 4 8 logical cores with the help of hyperthreading

ram: 12GB


Guest machine:

total cores: 4 CPU0, CPU1, CPU2 and CPU3

ram allocated: 6 GB


Why VM takes so much time? should i prefer virtualBox over Hyper-V in terms of performance? or do i need some kind of drivers on windows to optimize the performance of hyper-V??

NOTE: i've set the virtual machine process affinity and assigned 4 cores and then set its priority to high.

Thanks in advance.

:)

 

Hyper V deativication

Hi Geoffrey,

Hyper-V lets you run an operating system or computer system as a virtual machine on Windows. Before proceeding in disabling
Hyper-V, please create a backup of your files for security purposes.

To disable Hyper-V, please follow the steps below:

• On the Cortana search box, type Turn Windows Features on or off and press
  Enter.
• Look for the Hyper-V folder.
• Uncheck the tick-box next to the main Hyper-V folder and click
  OK.
• Restart your PC.

Should you have further questions, please let us know.

 

Where is the Hyper V Manager, How to I start it ?

I am trying to setup an XP virtual Machine on Windows 10 Pro.

I followed the steps in Neil Peterson article of 5/9/2016.

System Requirements - done - ok

Install Hyper-V - done - ok

Create a Virtual Switch - skip

Create a Virtual Machine

Create a Virtual Machine with Hyper-V Manager

These steps walk through how to manually create a virtual machine and deploy an operating system to this virtual machine.

• 
  In Hyper-V Manager, click Action > New >
  Virtual Machine to bring up the New
  

Uhhhhhhhhh - this step obviously implies one knows

1) Where the Hyper-V Manager is

2) How to start the Hyper-V Manager

Isn't that odd ?
