Why do you say that's silly? If your map reduce task does bulk deletes and let's say they do 100 at a time, then those 100 deletes are done in parallel. So that's 100x. So for each second of delete real time you're getting 100 seconds of CPU time. You should be pleased that instead of your task taking 11 hours to delete all your data it took only 15 minutes. Isn't that scalability? Isn't that what you're looking for? How many entities did you delete? How many indexes did you have (composite and single property)?
