It appears that at least one views plugin is using an inefficient joins.
Create a view, add "Hierarchy depth" and set it to 0. You'll get a query like this:
SELECT node_field_data.title AS node_field_data_title, node_field_data.nid AS nid, users_field_data_node_field_data.uid AS users_field_data_node_field_data_uid FROM
node_field_data node_field_data
INNER JOIN users_field_data users_field_data_node_field_data ON node_field_data.uid = users_field_data_node_field_data.uid
LEFT JOIN nested_set_field_parent_node nested_set_field_parent_node ON node_field_data.vid = nested_set_field_parent_node.revision_id
WHERE (nested_set_field_parent_node.depth = '0')
ORDER BY node_field_data_title ASC
LIMIT 35 OFFSET 25
I believe this nested_set_field_parent_node.revision_id
suffers from a lack of dedicated index. I'm finding it hard to replicate our performance issues outside of production so just creating the placeholder to get it started. Experimenting with an index.
