In our dev environment, with some add-ons installed for basic functionality (XenAtendo, XenPortal), the stock DB is tapping out at about 25 MB. Recently we've been trying out various styles, and had to uninstall a number of styles because they weren't a fit. We left maybe 3 styles currently for the user to choose, but it's still in dev and we're looking to add more styles.
I looked at the DB today in our source control and was astonished to see that it had doubled in size at 52.6 MB as a direct result of style testing. Is this normal if we've removed incompatible styles? What tables can I look at to potentially cut down on size?
