RE: Need more info about currently running queries
may be due to corrupted indexes it is taking long time. just re-org the table.if your table is InnoDB type then use below command to re-org it. mysql alter table table name type=InnoDB; based on size of the table it may execute for long time . for us it has solved performance issue.

As noted in my original message, I need much more detailed info. The crux of the problem is that I need to run a query that could take several hours when it's using indexes correctly, but it is not working correctly so it takes longer than I've been willing to wait (about 14 hours). I need to make changes to indexes and run the query again, but I don't want to wait hours until I know whether the change was effective or not. I really need a way to find out how far the query has progressed after 15 minutes so I can calculate how much improvement the changes made.
