Comment (by OllieJones):

 In the meantime (until the Future Release), for people who have
 performance problems with this query, may I, in shameless self-promotion,
 suggest:

 1. If necessary and possible, upgrade MySQL to, at a minimum, 5.7.

 2. Use the https://wordpress.org/plugins/index-wp-mysql-for-speed/ plugin
 to set up more efficient indexes on the postmeta and other tables.

 Doing these things should mitigate this problem without changes to core.

 Why? Please see my earlier response to this tix at
