In mysql-slow.log only appears this query many times:

SELECT count(*) as c FROM wp_posts WHERE ID IN (SELECT object_id FROM wp_term_relationships WHERE term_taxonomy_id = 542)

Any idea?

Why is your droplet so massive? you don’t need something that big for 300 concurrent visitors. I suggest you to start looking for holes in your droplet security, maybe is something else other than WP, do you have any other sites or php scripts running?

Yous MySQL is running on its own droplet? or into the same droplet as your website? Also can you let us know more about your droplet environment, webserver, php version, mysql version, etc? How is Total Cache configured?
