Re: Fedora 31 Does Not Use Swap Well?

Lukasz I am not sure if this is related to virtualization as I installed Windows 10 on VirtualBox and the performance was quite fine, but as soon as Android VM starts up, the performance suffers painfully, almost every event (e.g. mouse) has 2-5 seconds delay in response. I tried a virtual device (Android M) different from the current Android Q image, but performance is still very bad.  

The situation gets worse when the build and installation (deploying to the virtual device) starts.    
I'm going to find a way to evaluate my disk performance to see if that's the issue.

That is interesting. I also noticed choppy performance with Virtualbox,
so it may be something with virtualisation and not memory related. The
VM is doing fine, but host is a little slower during VM updates, or
other cpu/disk intensive tasks. I know this is normal, but I didn't
even noticed VM upgrades on Fedora 30.

Could You do something really heavy on Android VM in a background for
10 minutes and observe the hosts performance?
