[Bug 1897478] Re: ubuntu 20.04 is extremely slow to upgrade, install or uninstall any software and launch any of it

[Daniel van Vugt]

1. Can you benchmark your disk(s) with the 'Disks' app and/or 'hdparm
-t' and tell us what their speed is?

2. Please run this command to watch and check nothing is flooding the
system log while it is slow:

   journalctl -f

3. Please try uninstalling/disabling all of your extensions:
