Tíos, tengo un problema en uno de mis foros... cada cierto tiempo salta una query que es tremendamente lenta y hace que el foro vaya a pedales... utilizo vbulletin 3.8.1...
alguien podría aconsejarme? esta es la query
# Time: 110110 14:14:27
# User@Host: htcmania[htcmania] @ localhost []
# Query_time: 10.445781 Lock_time: 0.000155 Rows_sent: 30 Rows_examined: 1565698
use htcmania;
SET timestamp=1294665267;
SELECT user.*,usertextfield.*,userfield.*, user.userid, options,
IF(displaygroupid=0, user.usergroupid, displaygroupid) AS displaygroupid, infractiongroupid
,avatar.avatarpath,NOT ISNULL(customavatar.userid) AS hascustomavatar,customavatar.dateline AS avatardateline, customavatar.width AS avwidth, customavatar.height AS avheight
, IF((options & 512 AND user.userid <> 0), 0, lastactivity) AS lastvisittime
FROM user AS user
LEFT JOIN usertextfield AS usertextfield ON(usertextfield.userid=user.userid)
LEFT JOIN userfield AS userfield ON(userfield.userid=user.userid)
LEFT JOIN avatar AS avatar ON(avatar.avatarid = user.avatarid) LEFT JOIN customavatar AS customavatar ON(customavatar.userid = user.userid)
WHERE 1=1
AND (user.usergroupid IN (-1,6,11,10,12,15,16,14,7,9,5,2,13))
ORDER BY user.username asc
LIMIT 385410, 30;
Gracias!
