20134,Performance Problems with Complex Meta Queries,dominicp,,"I have noticed that when I have several criterion on a WP_Query meta query it can start to drastically impact performance. I don't know if this is just an unavoidable consequence of using the key/value data structure that WordPress does, but I wanted to bring it to the dev's attention now as it seems like 3.4 is going to involve some serious work on the Query component.

I have outlined a specific example of the problem in some detail here: [http://stackoverflow.com/q/8893160/931860], and I can definitely provide more details if someone feels they would be relevant.",enhancement,closed,normal,,Query,3.3.1,normal,wontfix,,
