If you do some poking around you will discover that Joom stats packages build gigantic databases in a very short time, even on relatively small sites. Additionally, there are so many calls to the DB that they can bring servers to their knees, particularly in a shared hosting environment.

The only people that I see that are pushing Joom stats packages are the ones writing them.

As is often the case, the long road is the better one. Learn to use the raw logs, or use a log based stats package like awstats.

In-software stats can be a real performance killer. If log-parsing statistics packages like awstats do not give you the information you want, you could sign up for Google Analytics. It gives great information about geographical location of users, pages they visit etc, but it takes some time to learn to use it. Implementation is simple, just a small piece of javascript code in the footer of each page.
