Support » Networking WordPress » multisite and wp_load_alloptions

  • When multisite is ‘on’ too many database queries are called, and bursts network bandwidth between web server and database server.

    The query is below.
    “SELECT option_name, option_value FROM wp_options WHERE autoload = ‘yes'”

    This is caused by a limitation of object cache and multisite.
    When multisite is on, wordpress cannot use wp_cache_get for that query in wp_load_alloptions function.

    Moreover, wp_load_alloptions is called when each get_option function is executed.
    If wp_options table has huge data (ex. serialized ‘rewrite_rule’), it costs so many time.
    Perhaps, it’s a solution of multisite confusion by wp_cache_get, but it causes another problem.

    I think, even no object cacheing is better than so many database query.

  • Are you having a problem or is this a suggestion for improvement?

    Yes, I have a problem.
    And try to solve that…

    Ok.. what is your problem? There are a lot of database queries.. but are they causing an error?

    If you are having a problem with too man options being loaded.. maybe you have too many plugins?

    I’m sorry, but it’s not clear what you want from the community.
