It's not a question of peak performance as much as consistency. Flat files aren't meant to work this way; that's largely why database applications work the way they do in the first place. If something like paging competes for drive access just long enough, the whole thing can go to hell. When you're opening a graphic or text file completely into memory to view or edit it? For that, sure, a flat file is faster. But when you're streaming through a flat file that's dozens of gigs in size, over an extended period of time while running the data into a memory and processor-intensive program at the same time? Try it, and just see how quickly that works over the length of the entire file compared to a database :)

If he was performing searches against data, sure, the database would be faster because it could take advantage of search algorithms, but even then data stored (sorted) in a binary-tree flat file would crush the database in terms of raw performance time because it wouldn't have deal with database overhead. -john -------------------------------------------------------------- ------------- Network with over 10,000 of the brightest minds in information security at the largest, most highly-anticipated industry event of the year.
