<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Mentions: don't prime mention results if the site/user has many users/friends.
Sites with huge amounts of users (and therefore probably many potential
friendships) can cause the primed result generation to be slow due to
the number of potential user name lookups/queries made.
Multisite has a function to help us decide if it?\226?\128?\153s a large network, but
it?\226?\128?\153s not available for regular WordPress, so we also check the logged
in user?\226?\128?\153s total friend count. (150 is Dunbar's number.)
In conjunction with the previous commit, this change should help make
the pre-cached result generation more performant.
Fixes <a href="http://buddypress.trac.wordpress.org/ticket/5950">#5950</a>. Props imath for original patch.</pre>
