I'm guessing that you have indexes on the 321st_stat table? If this is the
case, try dropping them before you do the insert, then rebuilding them.
MySQL is known to be slow at doing bulk inserts on indexed tables. Also,
updates are much faster than inserts since with inserts there are much more
disk IOs required.
