Support » Plugin: WP Super Cache » Preload Activated, but still many queries for supercached pages

  • samhat


    I have too many sql queries from WP. I have choosen the following settings at the bottom, but I still see queries for the posts that has already been cached.

    I open the mysql log file for a 1-2 minutes and check the executed queries.

    I see queries like below for cached pages.

    SELECT * FROM wp_posts WHERE ID = 12127 LIMIT 1

    Query SELECT t.*, tt.* FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON tt.term_id = t.term_id INNER JOIN wp_term_relationships AS tr ON tr.term_taxonomy_id = tt.term_taxonomy_id WHERE tt.taxonomy IN ('category') AND tr.object_id IN (12127) ORDER BY ASC

    First select query is executed 99 times in 1-2 minutes.

    Is it normal to see sql queries for already cached pages. Shouldn’t super cache static html pages without any php and sql execution.

    I can see that supercache directory created the cache file for the post with the ID 12127.

    Trying to understand if super cache is working right.

    Thanks for any suggestions.

    – Caching ON
    – Use mod_rewrite to serve cache files. (Recommended)
    – Compress pages
    – Don’t cache pages for known users
    – Cache rebuild
    – Lock down enabled
    – Preload – Refresh preloaded cache files every – 2880
