Commit after delete

FilipFryMay 7 2010 — edited May 10 2010
I have a job that process data for last 7 days. Most of data(90%) is processed in first iteration(first day) after what i delete processed data and do a commit. What is strange is that job continues to work slow as if there is same amount of data like there was before deleting. How to improve performances?
