How to optimize ‘select found_rows()’ query? Several ‘high load average’ alerts daily
This should not break pagination: add_filter(‘pre_get_posts’, ‘optimized_get_posts’, 100); function optimized_get_posts() { global $wp_query, $wpdb; $wp_query->query_vars[‘no_found_rows’] = 1; $wp_query->found_posts = $wpdb->get_var( “SELECT COUNT(*) FROM wp_posts WHERE 1=1 AND wp_posts.post_type=”post” AND (wp_posts.post_status=”publish” OR wp_posts.post_status=”private”)” ); $wp_query->found_posts = apply_filters_ref_array( ‘found_posts’, array( $wp_query->found_posts, &$wp_query ) ); if($wp_query->query_vars[‘posts_per_page’] <= 0) { $wp_query->max_num_pages = 0; } else { $wp_query->max_num_pages = ceil($wp_query->found_posts … Read more

Pippin Williamson embeds WPSM in his Easy Digital Downloads plugin. Given Pippin’s review and Eric being such a pro-old-timer-wp-ninja, I wouldn’t look no … Read more
