 Hi, Wordpress have a issue when website has many users. Because wordpress
 will load all user when page load for update metadata cache for the user
 objects (function update_meta_cache)
 Avg query time execute is 0.0001, if my website have 10.000 users. Page
 will load delay 1 second.

 Like this images in my website.

 I have over 17k users. Time mysql execute avg = 0.0002 => My web will
 delay 3.4 second + about a few hundreds request other = 5-6s

 Hope wordpress team will fix!
 Sorry my bad english.
