xf_session = MyISAM = 0.03s
xf_session = Innodb = 0.10 - .015s
That's over a 3 fold increase from this one query:
UPDATE `xf_session` SET `expiry_date` = ? WHERE (session_id = '2cb236cf10c72722230ac458f575e89e')
Is there anything I can do to speed things up, other than switching to MyISAM? I'd like to avoid doing so, as if the table is marked as crashed then it would bring the forum down (and it'll happen at some point!).
