Do you have complete execution stats, including fetches, backout\purge\expunge and so on ? 2. Do you run SS or CS ? If SS, you should know that tools such as isql\IBE reports stats for the whole database activity, not isolated by the single statement. 3. Do you have triggers for DELETE on this table ?
