Slow queries

I just installed query monitor wp plugin, and what I found out that on post page there are 7 slow queries related to Contextual Related Posts plugin (i’m showing 6 related post). No other slow queries of wordpress or any other pluging, so it’s not a server performance issue.
Here’s the slow queries:

SELECT wp_posts.*, MATCH (wp_posts.post_title,wp_posts.post_content) AGAINST ('>>>>>> POST CONTENT <<<<<<') as score
FROM wp_posts
WHERE 1=1
AND ( ( wp_posts.post_date >= '2012-02-20 00:00:00'
AND wp_posts.post_date <= '2022-02-17 15:10:45' ) )
AND wp_posts.ID NOT IN (97709)
AND wp_posts.post_type = 'post'
AND ((wp_posts.post_status = 'publish'
OR wp_posts.post_status = 'inherit'))
AND MATCH (wp_posts.post_title,wp_posts.post_content) AGAINST ('>>>>>> POST CONTENT <<<<<<')
ORDER BY score DESC
LIMIT 0, 6

There’s a way to avoid this?
