updatedb (which is used for
locate) seem to run at startup every day on some machines. This causes the machine to be much slower until they have finished, which is annoying.
You can disable tracker if you don't use it. Open a console window and navigate to
/etc/xdg/autostart/ and edit the file
trackerd.desktop as root (using sudo). Add the line
to the end of the file. do the same with the file
This will disable the tracker for all users on the machine. To disable the tracker for a specific user only follow the guide on https://wiki.ubuntu.com/Tracker, which is where I found this solution too.
Cleaning up updatedb
updatedb is used to keep track of all files one your harddrive so that you can search them using
locate. However there are on some machines installed several scripts that will run this program every time it boots and thus slow it down. Having this database updated every day seems like overkill to me, weekly should be sufficient.
Open a console window and navigate to
/etc/cron.daily/, list the files there. If you find the files find.notslocate or find.notslocate.dpkg-new remove them using
sudo rm find.notslocate
sudo rm find.notslocate.dpkg-new
Check to see if you have both
slocate files you only need one of them.
mlocate is the prefered locate by Ubuntu so lets remove
sudo apt-get purge slocate
to remove it. It might say that
slocate is already uninstalled, in that case remove the slocate script by typing
sudo rm slocate
Finally lets move all the scripts that run
cron.weekly (which make them run weekly instead of daily). From the cron.daily folder type:
sudo mv mlocate ../cron.weekly/.
sudo mv find ../cron.weekly/.
