Changeset 41613 for trunk/src/wp-includes/ms-functions.php

Message:

Users: Introduce the concept of a large site in order to speed up the Users screen when there are many users.

Calling the count_users() function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
count_users() can be avoided entirely while still displaying the total count for users.

This introduces some new functions:

• wp_is_large_user_count()
• wp_get_active_user_count()
• wp_update_active_user_count()

A corresponding wp_is_large_user_count filter is also introduced.

Props tharsheblows, johnbillion
