I could make a buffer of N lines and read them, I guess. I kinda figured at 1 line a second, PHP and the OS would have no problem buffering from the disk. > Another thought.. can you use database replication here?

This data's coming from an external source. Replication is probably not gonna happen. Though I am going to ask for a timestamp column so I can ignore rows that haven't changed since my last import. That should kill about 90% of the MySQL processing, which seems to be the biggest CPU sink here. If that happens, I can probably change the sleep to usleep and a quarter second or so. -- Like Music? http://l-i-e.com/artists.htm
