If you have 1641 zip files, either you just made an enormous number of changes, or you aren't syncing your devices very often. To get that number down to a more reasonable size, first go to the Sync preferences panel on the desktop and use the Show Clients display to make sure you don't have any clients that haven't synced recently. If there are some listed that are no longer relevant, or are duplicates, unregister them. Next, sync all of your current clients. Wait an hour. Sync them all again, and the database should compact and you'll find out why most everyone says that 1.6 is fast.
