It came from a database. Originally I was getting just the data I wanted using SQL, but that was taking too long also. I was selecting just the messages I wanted, then for each one of those doing another query to get the data within the time diff of each. That was resulting in tens of thousands of queries. So I changed it to pull all the potential matches at once and then process it in python. -- http://mail.python.org/mailman/listinfo/python-list
