Extremely High CPU Usage
The following cron job script has been reported to me by my host as using a lot of CPU. To the point where our site has started to return error messages while it is running. I am looking for suggestions on how to optimize any way possible.
PHP Code:
// ---------------------------------------------------
// Start Set PHP Environment
// ---------------------------------------------------
error_reporting(E_ALL & ~E_NOTICE);
if (!is_object($vbulletin->db))
{
echo "No vBulletin Found!";
exit;
}
// ---------------------------------------------------
// Start Cronjob
// ---------------------------------------------------

The main SQL
PHP Code:
SELECT userfield.field5, userfield.field11, userfield.userid FROM userfield INNER JOIN user ON user.userid = userfield.userid AND userfield.field5 > '' WHERE usergroupid IN (6,48,52,51,26,58,60,55,46)
Returns 87 Results. The while statement runs 87 times.
