high consumption

Hi friends download this extension for testing and I must admit it is amazing everything perfect but after 2 days when backing up sql I realized that their weight was greater than 22mb when previously before installing this extension you tell weighed only 1mb my partner on the web and told me it was critical because for every person who walked through the phone is 22MB consume my bandwidth limit of 20000 to have a MB per month might have been fatal now my question is this true that consume as much bandwidth for each person entering or only notice the alteration in the sql greetings and respect

22Mb is the size of WURFL (database of mobile devices capabilities). This database is used to determine device screen size, and is used on server side only (so, it doesn't increase html page size).
