 Catching up with the latest comments here, the
 [https://wordpress.org/plugins/index-wp-mysql-for-speed/ Index WP MySQL
 For Speed] plugin suggested in comment:86 looks quite impressive, and the
 theory behind it] is also a recommended reading.

 This is also being discussed in the new Performance team repo:
 [https://github.com/WordPress/performance/issues/132 Revisit indexes for
 DB performance]. With enough eyes and testing, I believe it could be one
 of the team's focuses in near future.

 In the meantime, I would like to revisit [attachment:"33885.5.diff"] as
 suggested in comment:61, which should improve performance for those using
 persistent object caching like Memcached or Redis. This could also use
 some testing.
