Possible to Speed up query?

This is timing after Checkout -> Order Received.
Is it possible to speed these results from Query Monitor up which relate to GTM4WP? Combined they are taking almost 0.6 seconds

I’ve dumped the relevant results below and added [QUERY —> …] to better readability.

[QUERY --> 
SELECT SUM(meta2.meta_value)
FROM wp_posts as posts
LEFT JOIN wp_postmeta AS meta
ON posts.ID = meta.post_id
LEFT JOIN wp_postmeta AS meta2
ON posts.ID = meta2.post_id
WHERE meta.meta_key = '_customer_user'
AND meta.meta_value = '2'
AND posts.post_type = 'shop_order'
AND posts.post_status IN ( 'wc-processing','wc-completed' )
AND meta2.meta_key = '_order_total']
[ CALLER -->> WC_Customer_Data_Store->get_total_spent]
