Re: Question on slow queries

Well, let's study the third query -- UPDATE users. It's averaging 364ms; it might be possible to improve it.

Please provide the full statement, the SHOW CREATE TABLE, and the size of the table.

COMMIT is misleading, since we can't see what the transaction was doing.

Also provide
SHOW VARIABLES LIKE 'innodb%';

How big are all the InnoDB tables combined? Is it bigger than 640M? How much RAM is available?
