so you're missing about 25 minutes, and maybe 5 minutes is spent post
processing, so thats 20 minutes spent in the data insertion?
inserting one row at a time? or in batches? remeber a database
server is going to do commits after each transaction, which forces the
data to be flushed to disk. 4.5 million seperate row transactions,
yeah, I could see that taking some time, plus add that many network
round trips, etcetc. if the db server just has a single SATA disk,
you're doing 9 million committed writes combined to the two tables?
20 minutes for 9 million inserts, thats 7500 per second.
