Function: count_users
count_users( string $strategy, integer | null $site_id )
Count number of users who have each of the user roles.
Assumes there are neither duplicated nor orphaned capabilities meta_values. Assumes role names are unique phrases. Same assumption made by WP_User_Query::prepare_query() Using $strategy = 'time' this is CPU-intensive and should handle around 10^7 users. Using $strategy = 'memory' this is memory-intensive and should handle around 10^5 users, but see WP Bug #12257.
