How to remove Zeitgeist in Ubuntu and why

In my desktop I use Xubuntu 12.04, and today i noticed that this distribution shippedd by default the Zeitgeist daemon, a thing that I’m not using at all and that is using resources of my system, so I’ve decided to remove this daemon totally from my system, please note that if you use Gnome 3 or Unity you could have some side effect, or perhaps the system will just become more faster, like the author of the article: Removing Zeitgeist Sped Up Unity .
