[Resolved] Slow Windows 10 guest

[ondramas]

Hi, my Windows 10 guest OS runs very slow. I'm not sure if it can be improved but I'd be very happy if somebody had a look at my log file and maybe suggested some changes.
If you need more information, I'm willing to provide it. I just don't know what else is needed.
Thank you in advance.

Hi @ondramas! I assume that you use an OS X host according to your log, can I ask if you have guest additions installed? Besides, if your Mac has enough RAM, you can try to increase the RAM allocation to the Windows 10 Guest. If possible, you can try to turn off Windows Defender as it will use RAM and system resources, causing the VM to become slow.
You can google some tips to speed the VM up, too.

Hope this helped.

In order for a VBox.log to have any gravitas, we need to see a complete VBox.log, from a complete VM run, where the problem occurs. Yours is from a saved-state to a saved-state, we're missing crucial information:

• Start the VM from cold-boot (not from a paused or saved state) / Observe or recreate the problem / Shutdown the VM (force close it if you have to).
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response.

I'm sorry, but I couldn't allow a link to a website on your first post, I've removed the (obfuscated) URL.

I attach the new log.
Yes, I have the Guest Additions installed and inserted. I tried to turn off the Windows Defender but it took so long with the actual speed so I gave up...
Thank you in advance for your help

I found out what was the problem. I forgot that my mac has only 2 cores which I assigned to the VM. When I lowered the processors count to 1 the VM started to run more smoothly. But still, if you find something that could improve my VM speed, I would be glad.

Any particular reason why you decided to override the template defaults, and go with an unsupported, experimental, OSX-guests-only option? Please change it back to the default PIIX3. Do not change the defaults unless you know what you're getting into.

Go to the VM Settings » Display » Screen. Enable 3D acceleration. Increase the VRAM to the max 256 MB.

Always eject the Guest Additions (GAs) ISO once you're done with the installation.

But the most important culprit is (as you found out) the fact that you were giving all your CPUs to your Guest.

Marking as [Resolved].
