Having the traffic hit different *tables* (wp_posts, wp_term_relationships)
makes an enormous difference, unlike having separate *databases*, which
performance-wise is the same as if they were in different tables of the
same DB. The good news is in almost all cases WP Multisite already splits
sites across tables, so the performance benefits are automatic.
