Can this query be fixed so it doesn't take almost 7 seconds to load?

Code: 
SELECT thread.*
    ,
    user.*, IF(user.username IS NULL, thread.username, user.username) AS username,
    deletion_log.delete_date, deletion_log.delete_reason,
    deletion_log.delete_user_id, deletion_log.delete_username,
        IF(thread_read.thread_read_date > 1483027983, thread_read.thread_read_date, 1483027983) AS thread_read_date,
    IF(thread_watch.user_id IS NULL, 0,
        IF(thread_watch.email_subscribe, 'watch_email', 'watch_no_email')) AS thread_is_watched,
    thread_user_post.post_count AS user_post_count,
    pr_cache.rating_cache
FROM xf_thread AS thread

    LEFT JOIN xf_user AS user ON
        (user.user_id = thread.user_id)

        ON (thread_watch.thread_id = thread.thread_id

That query is not slow because of Post Ratings. If you remove everything added by post ratings it is still having to fetch and sort a large number of rows

(i.e. the lines containing 'pr_cache')

Thanks. Is it a default XF query without your addition? It doesn't seem to be pulling any other 3rd party data.

Yes it appears to be the query that is used when viewing individual forums, ie /forums/xxx

It is still present and still accesses a large number of rows with Post Ratings completely disabled

This is a semi-custom query by an add-on. XenForo queries should have some sort of limit clause to explicitly prevent pulling every non-sticky thread in the forum.

There was a line missing, it is 'limit 20' on mine (but still reporting a large number of rows in explain)

Though not sure if it is a core query or from another addon
 
How do i add boxes like this?
I can't seem to figure it out even though I tried.

I think it is a core query. One of the reasons this can get so slow, is that MySQL does early row lookup and effectively gathers every select data for every row examined.

@BamaStangGuy can you try this add-on? https://xenforo.com/community/resources/optimized-list-queries-by-xon.4487/
It implements some SQL rewriting to implement late row lookup which may help.

Damn, I'ld say start disabling stuff until it gets better. Might be something weird environmentally.

I have a support ticket opened as well. It looks like it is a completely stock query and seems to only be slow due to the extras collected for moderators/admins.

As a guest the page loads very quickly.
 
Hi @Luke F. I have some issue with PR count. I guess it's connected with positive|neutral|negative ratings which have changed some time ago. It looks like some neutral ratings count like positive and otherwise. Could you help me to fix this?
Here're an examples

That looks like it is from a custom theme, there is no built in feature that looks like that

Have you tried running recount ratings in the admin cp? I would recommend taking a backup first just in case

Has this ever been updated to not show banned members ?

Does anyone know where to add a conditional or something to filter out the banned members?
Click to expand...
Or maybe a snippet added to the query that pulls that data, to exclude banned users.
(I will look for the variable name)
 
This query is showing up in our slow query log:

@Luke F could you possibly look into adding a feature where we can remove a certain user's ratings that he has given in a certain time? I have some users who like to ratings boost and spams every post with a rating.

Hey @Luke F any possible thought on this idea? Would be very handy for staff and moderators on sites against those who abuse this feature.
 
Been a while, just starting back up. How would I go about redownloading the files? Starting up a community again and I lost my old download. Email might've been deleted.
