Lately it feels like one of my older Xubuntu 18.04 installs seems to booting slower, and it also seems to be responding a little slower. I tried running bleachbit to clean as much of system as I know how. I also tried defragmenting the hard drive. Since everyone is saying that the new Ubuntu 20.04 is so much faster. I decide to swap out the hard drive and install Xubuntu 20.04. In my experience it also seemed to be a little slow. Next I swapped out the hard drive again, and tried installing Linux Lite 4.8. I was surprised it was behaving more like I expected Xubuntu to behave. Right as I'm writing this, I'm going to erase Linux Lite 4.8 and try another install of Xubuntu 20.4. I want to see if the speed difference is the hard drive or maybe it's the Nvidia drivers.
