The database isn't very huge at the moment because of the constant purging of old threads, it currently stands at about 1.5gb+ and will continue to grow.

I'm working on an archiving system at the moment that will allow threads to be archived. The technical limitations on the number of posts are currently being overcomed with new hardware, code changes and this new archiving system.

If we have never purged any threads before, the current DB size would stand at around 8GB.
