18968,Remove some term cache misses,johnbillion,,"On post listing screens a database query is performed for each taxonomy on each post. We can hit the term cache instead by using `get_the_terms()` in place of `wp_get_object_terms()` and `wp_get_post_terms()`.

By default, this change won't impact performance because the term cache isn't primed at this point, but on a site using a persistent object cache it'll hit the term cache each time instead of performing a database query. This saves `{numberofposts} × {numberoftaxonomies}` queries which can be quite a few on custom post type screens which display several taxonomy columns.",enhancement,new,normal,Awaiting Review,Performance,3.3,normal,,has-patch,
