9007,Poor get_category_children() performance; rewrite to use get_term_children(),_timk,ryan,"I'm working on a WordPress site with a few thousand categories.  The categories are structured a bit, with one master category, a few organizational subcategories, and then the bulk of the remaining categories under those.  

I'm looking to get a list of children for one of the middle-tier categories.  Running get_categories() with the 'child_of' parameter calls get_category_children().  This call hits the 30-second server time limit.  Outside the web environment, get_category_children() takes around a minute and 40 seconds to build a list of 589 categories on a relatively powerful desktop PC.

I'll attach a revised, non-recursive implementation of get_category_children() that uses get_term_children() and runs several orders of magnitude faster than the original in my environment.  It returns almost instantly.",defect (bug),closed,normal,2.8,Taxonomy,2.7,normal,fixed,has-patch get_category_children,
