I have noticed that tracker-store and tracker-miner-fs together take almost 60-70% of the CPU all the time leaving nothing for the other applications (openSUSE 12.1 64 bit, KDE 4.8.3. I have disabled nepomuk from auto starting, but haven't been able to find yet how to disable these, so i have to just suspend/kill both these processes manually every time on login. Does anyone know how to disable them?
