MySQL Forums :: InnoDB :: COMMIT function take too much time to respond

Thanks. Alas, no good clues.

A side issue...
UPDATE `gc_monster` SET `loyalty` = CASE `id` WHEN '11' THEN 100 WHEN '12' THEN 100 WHEN '13' THEN 100 ELSE `loyalty` END WHERE `id` IN (11, 12, 13) LIMIT 3;
could be written
UPDATE `gc_monster` SET `loyalty` = 100 ELSE WHERE `id` IN (11, 12, 13);
The UPDATE in the PNG, also has a constant value (23), so I am wondering whether this the normal case?

Another puzzle... I see that the COMMIT and the UPDATE all have about the same "Time" (about 1333 seconds). Are you running with autocommit on or off? Are you using BEGIN (START TRANSACTION)? What comes _before_ the UPDATE? Are there several statements between the BEGIN and COMMIT? And, maybe, the UPDATE is the last one? Is something else leading to a 20 minute delay? Is that delay pretty consistent in other cases?
