Trying to Identify Query that Causes Slow DB Running

[Banana]

Hi

It has been identified that the following query is being run frequently on our database causing it to run very slowly when load is higher than normal


SELECT COUNT(*) AS count FROM post AS post LEFT JOIN threadread AS threadread ON (threadread.threadid = post.threadid AND threadread.userid = 0) WHERE dateline >= 1518365046 AND dateline > IF(threadread.readtime IS NULL, 1538597345, threadread.readtime)

Is it possible to know which feature is causing this query to run please?

Here's my current process list from mysql for example

+--------+-------------+-----------+------------+---------+------+--------------+---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+----------+
