  • You can’t use is_admin() function for verifying user access.

    An even more basic problem is that WordPress has not been loaded when the DB variables are defined. That means it is impossible to do what you want using WordPress functions.

    The most basic problem is that what you’re requesting makes no sense. If admins used a different database, nothing they did in the admin panel would have any effect on the rest of the users — they would essentially be running a different version of WordPress. (This, BTW, is the basic idea behind Multisite.)

    The best way to decrease DB load is to determine whether any plugins are causing a problem, and then deactivate them. You may simply have too many active plugins, in which case you’ll need to decide which ones to keep and which ones to deactivate.

    You should also check your theme as well; some WordPress themes are unnecessarily hard on the database.
