Re: AW: InnoDB and foreign keys

If you could post your table schema (SHOW CREATE TABLE table_name) and then give an example of the query that is slow on InnoDB that would help us give a better analysis. Right now it sounds like something is wrong, InnoDB is likely to be slightly slower than MyISAM because of transaction overhead

Suggestions? Check your indexes. It sounds as though they aren't what they used to be. When you converted to InnoDB, did you accidentally move the data to a slower drive? If so, you may want to move it back to where you had the MyISAM tables. Shawn Green Database Administrator Unimin Corporatio
