Large query against all wp_posts and wp_ap_qameta for no apparent reason.

Why does this query have to run on a category page?  There seems to be no use for this on a category page but its firing when I go to any category page.  This is a query that goes against the entire tables of wp_posts and wp_ap_qameta.  Can it just be prevented from being run by any pages?  What calls this? (or could you tell me how I can debug this to stop it from being called?)   Is it possible something is setup to trigger this additional call for now reason?

1. WP_Query->get_posts()
    wp-includes/class-wp-query.php:2846

SELECT wp_posts.*, qameta.*, qameta.votes_up – qameta.votes_down AS votes_net
FROM wp_posts
LEFT JOIN wp_term_relationships
ON (wp_posts.ID = wp_term_relationships.object_id)
LEFT JOIN wp_ap_qameta qameta
ON qameta.post_id = wp_posts.ID
WHERE 1=1
AND ( wp_term_relationships.term_taxonomy_id IN (327689) )
AND wp_posts.post_type = ‘question’
AND ((wp_posts.post_status = ‘publish’
OR wp_posts.post_status = ‘trash’
OR wp_posts.post_status = ‘moderate’
OR wp_posts.post_status = ‘private_post’)
OR ( wp_posts.post_author = 1
AND wp_posts.post_status IN (‘publish’, ‘private_post’, ‘trash’, ‘moderate’) ) )
GROUP BY wp_posts.ID
ORDER BY CASE
WHEN IFNULL(qameta.featured, 0) =1
THEN 1
ELSE 2
END ASC, qameta.last_updated DESC
LIMIT 0, 20

Separately.  The question page itself seems to call this Query again which is unnecessary for that specific page.  Why would this be?

SELECT count(wp_posts.ID) FROM wp_posts  LEFT JOIN wp_ap_qameta qameta ON qameta.post_id = wp_posts.ID WHERE 1=1  AND wp_posts.post_type = ‘question’ AND ((wp_posts.post_status = ‘publish’ OR wp_posts.post_status = ‘trash’ OR wp_posts.post_status = ‘moderate’ OR wp_posts.post_status = ‘private_post’) OR ( wp_posts.post_author = 1 AND wp_posts.post_status IN (‘publish’, ‘private_post’, ‘trash’, ‘moderate’) ) )
