Today the CPU usage and sound of the system fan drove me crazy. The evil was the mds_stores process.
mds_stores is a part of Spotlight and it’s indexing engine.
After a small amount of time i decided to turn that shit off. I do not use the Search of OS X so i do not need that thing.
to turn the indexing off write that to your Terminal:
sudo mdutil -a -i off
maybe you want the indexing back:
sudo mdutil -a -i on
Here is the Man Page of mdutil:
