Hi!
@ Blinmakerivan[...]In the LL4.x series I know one could gain performance if not planning on using VirtualBox and removing.[...]
I had trouble because of VBox too. It seems that loads a lot of modules and that takes lots of time. I gave up using VBox on Lenovo T400 because of the low level of resources.
On the current machine I might use it, I have enough resources, but the only reason to use it would be to test a distro. I gave up this idea because it's irrelevant if a distro runs in a VM. I prefer to test it on a real machine and the easiest way is to use an external drive and placing the GRUB on the respective drive.
So, from this perspective, running a VM is useless for me.
I experienced this kind of delay with three (four, actually) distros: Linux Mint, Manjaro and Linux Lite. Seems that on Redcore Linux (a friendly Gentoo) behaves the same.
I assume no one cares now for this kind of delay, due to the current standard configurations available on the market.
However, there are many like me, who want to use the resources for a different purpose than loading useless stuff...
Hope this info will help you make the best decision for yourself!
Best regards.
