for ex. sudo apt install gthumb will spend a small time doing everything else. When it calls update-mime-database /usr/share/mime it spends more than 10 minutes!!!
I wonder if I could install everything w/o calling update-mime-database, then manually call it with ionice update-mime-database /usr/share/mime (as it also generates a lot of IO despite writing just about 4MB iotop) in a child/background process?
any other tip/idea?
