Delete Pend Requests
Using Jamroom
Something is tying your DB up - it's not the delete requests - they are already heavily optimized (all the DS queries have been heavily optimized). 20-40 seconds means your server is either REALLY overloaded or something else has "locked" the database. If you have SQL backups running in a control panel you might want to check there as they will often lock tables while the backup is running.
