When do you commit these inserts? I occasionally found similiar problems, when I do heavy inserting/updating within one single transaction. First all runs fast, after some time everything slows down. If I commit the inserts every some 1000 rows (large rows, small engine), this phenomenon does not occur. Maybe some buffer chokes if the transaction ist too big. In your case I'd recommend to commit after every one or two million rows (if possible). Regards, Frank.
