Woocommerce slow query

Hi, my on my store I’m using Query Monitor and on product pages it shows over 100 slow queries. And because of that my load time are over 30 seconds or more. I asked my hosting provider (A2 Hosting) about it and they confirmed that there is no problem on their side and this may be plugin problem. The queries that are slow looks like this:

SELECT t.*, tt.*
FROM wp_terms AS t
INNER JOIN wp_term_taxonomy AS tt
ON t.term_id = tt.term_id
INNER JOIN wp_term_relationships AS tr
ON tr.term_taxonomy_id = tt.term_taxonomy_id
WHERE tt.taxonomy IN (‘product_shipping_class’)
AND tr.object_id IN (878)
ORDER BY t.name ASC

and

SELECT DISTINCT t.*, tt.*, tm.meta_value
FROM wp_terms AS t
INNER JOIN wp_term_taxonomy AS tt
ON t.term_id = tt.term_id
INNER JOIN wp_term_relationships AS tr
ON tr.term_taxonomy_id = tt.term_taxonomy_id
LEFT JOIN wp_termmeta AS tm
ON (t.term_id = tm.term_id
AND tm.meta_key = ‘order’)
WHERE tt.taxonomy IN (‘product_cat’)
AND tr.object_id IN (828)
ORDER BY tm.meta_value+0 ASC, t.name ASC

and both are called by:
WP_Term_Query->get_terms()
wp-includes/class-wp-term-query.php:695

I’m adding some images maybe it helps:
