我怎样才能改进这个wordpress查询,它让网站变得非常慢!
SELECT wp_posts.ID
FROM wp_posts
INNER JOIN wp_postmeta
ON ( wp_posts.ID = wp_postmeta.post_id ) JOIN wp_icl_translations t
ON wp_posts.ID = t.element_id
AND t.element_type = CONCAT(\'post_\', wp_posts.post_type)
WHERE 1=1
AND ( wp_postmeta.meta_key = \'post_views_count\' )
AND wp_posts.post_type = \'post\'
AND ((wp_posts.post_status = \'publish\'))
AND ( ( t.language_code = \'fr\'
AND wp_posts.post_type IN (\'post\',\'page\',\'attachment\',\'grille\',\'podcast\',\'equipe\' ) )
OR wp_posts.post_type NOT IN (\'post\',\'page\',\'attachment\',\'grille\',\'podcast\',\'equipe\' ) )
GROUP BY wp_posts.ID
ORDER BY wp_postmeta.meta_value+0 DESC
LIMIT 0, 3
