Every gnome users should take this suggestion seriously.
I’ve a quiet fast notebook with nvram ssd disk on it. But as you see below, those tracker-extract and their tracker-xxx families of processes works more than 4 hours with %100 cpu on one core:
ps -eo pid,lstart,etime,cmd | grep tracker

1518 Sat Jan 12 21:04:44 2019 04:23:01 /usr/lib/tracker/tracker-miner-user-guides
1519 Sat Jan 12 21:04:44 2019 04:23:01 /usr/lib/tracker/tracker-miner-fs
1523 Sat Jan 12 21:04:44 2019 04:23:01 /usr/lib/tracker/tracker-store
1529 Sat Jan 12 21:04:44 2019 04:23:01 /usr/lib/tracker/tracker-extract
What they are wanting to do? How it will be helpful for me? What is the difference from a spyware? It is very annoying and I just realized it when my battery start getting low frequently because of the high cpu usage.
Long story short, just use following command and remove the whole tracker-xxx staff:
$ sudo apt remove tracker
apt will say that
gnome-corepackage also be removed, don’t be afraid, it is just a meta package and you don’t need it after initial Debian installation.
