You should try deleting in smaller batches if you can. I've found things go a lot quicker doing it that way and you don't lock up your table for long durations if you want to stick with MyISAM.

Subject: Need to speed up deletes


I need to delete 200,000 rows from an 8 million row MyISAM table using an index. It's taking 20 minutes which is quite slow. Is there any way to speed it up? TIA
