  • How to optimize user table

    Hi, my forum is reaching almost 5m register user which make the user table about 7.5GB. It also cause timeout when search user in admincp, usergroup management page, moderator permission, and it all seems related to user table. What should I do here to improve this.

    Here is some slowquery log


    # Query_time: 199.650164 Lock_time: 0.000047 Rows_sent: 69 Rows_examined: 157
    SET timestamp=1523406231;
    SELECT user.*, usergroup.usergroupid
    FROM usergroup AS usergroup
    INNER JOIN user AS user ON(user.usergroupid = usergroup.usergroupid OR FIND_IN_SET(usergroup.usergroupid, user.membergroupids))
    WHERE (usergroup.adminpermissions & 1)
    GROUP BY user.userid
    ORDER BY user.username
    /**getSuperGroups**/;


    # Query_time: 130.292878 Lock_time: 0.000030 Rows_sent: 3989532 Rows_examined: 5073500
    SET timestamp=1523406088;
    SELECT `usergroupid`,`membergroupids` FROM user
    WHERE `membergroupids` <> '';

    You will have to create an issue report here: http://tracker.vbulletin.com/secure/...91&issuetype=1

    The developers will have to work on the query to make it more efficient. Until then, you would have to increase the timeout or delete inactive users from the site.

        What is the output of this query:

        Code:
        SHOW CREATE TABLE user;

          Code:

          I only added one new field account_id and it store around 20 char for each user.

            Thanks. Another question from our lead developer...

            Do you use the Secondary Usergroup system a lot?

            The way this is stored currently can cause a lot of performance issues. We basically store it as a list of comma separated values. If you do use secondary groups, we will most likely need a copy of your database setup for testing and performance purposes. The developers can create a database with a lot of users but if we don't have all the nuances, it will be difficult to recreate the issue.
