W7+64b gest : so slow on W10-64 host

Post by Alexis81 »

Hi,
I use a lot of Win7-64b VM on laptop DELL W10-64b.
All VM are so slow.

Hyper-V is disable on host W10.
On host W7:
- PAE/NX is activated
- VT-x/AMD-x is activated
- 6 cores are activated at 100% power allocated
- 23616 mo memory allocated.

How to solve it ?
Thank you very much for your help.

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

You're running at full HD without accelerated graphics. Try enabling 2D and 3D acceleration.

23GB RAM seems like a lot to give to a VM?

With 3D activated it's not faster...

Please post a new log, so we can see if 3D has been activated in the VM.

You seem to have maxed out VM cores, leaving nothing for the host. That was not part of the instructions.

To cut the inevitable comeback short: threads are not cores. According to Intel your CPU has 6 cores. 2 cores to the VM is usually ideal, and you already had that.

Once that's fixed I suggest you look at the task list for the guest OS, to see what's hogging CPU or I/O.

6 cores was a over test... But With 2 cores it's little better...

Do you have so-called security software (e.g. Anti-virus) installed on the host? If yes, for a test, uninstall it, reboot the host, and see if the problem persists.
