I just dumped my XF database for the first time (new customer/new test installation) in preparation for doing some test imports. I have 5 add-ons and 4 styles installed. Minimal data to speak of yet as this is a newly installed forum with just some sample forums and threads and 3 mock user accounts to test things out before importing. The MySQL dump yielded a SQL file over 75 MB in size which really surprised me being so large. My old vBulletin forum has about 10 years worth of data in it, over 50 styles installed and dozens of add-ons and it comes to about 60 MB when dumped. What in the world makes XF's database so huge so early in the game before any real data is added when there are so few add-ons and styles installed by comparison?
